 [<ffffffff81084b0f>] __do_softirq+0xef/0x280

The symptom observed is multiple async handles get queued for same index
thus causing leak in buffers posted to FW.

The root cause is:
- async handle is continued to be used even if it does not match the
completion.
- list_move operation done on already filled index.

1. Remove use of writables, host_write_ptr and ep_read_ptr.
2. Remove consumed logic to update writables. Instead, use only
free_entries to do the accounting of handles to be posted back.
3. Remove busy_list, instead use simple slot to index handles.
4. Added check no data, header less and overflow to make sure
all async_handles are flushed in error cases.
5. Added code to verify gathering of handles to form PDU by
checking final bit before forwarding PDU.
6. Added code to catch mismatch with CQE and handle gracefully.
7. Use AMAP, traverse cri_wait_queue list to post buffers, log
"async PDU" related errors.
8. Rearranged few data structures and added comments in init &
processing path.
9. Added WARN_ONs to catch any HD ring corruption.

50a4b824be scsi: be2iscsi: Fix to make boot discovery non-blocking
Boot work involves:
1. Find and fetch configured boot session and its handle.
2. Attempt to open the session if its not.
3. Get the session details for boot kset creation.
4. Logout of that session owned by FW.
5. Create boot kset for session details.

All these actions were done in blocking call with retries in global wq.
Other works in wq suffered if the IOCTLs stalled or timed out.

This change moves all the boot work to make it non-blocking.
The work queued in global wq just issues the IOCTL depending on the action
to be taken and mcc wq schedules work depending on status of the IOCTL.
Initial boot_work is started on link and ASYNC event.

The other code changes move all boot related functions in one place and
follow naming conventions.

b7ab35b133 be2iscsi: Fix processing CQE before connection resources are freed
Driver should process the completion queue entries before a connection
 resources are freed. While running mixed traffic due to latency, driver
 processes the CQE after the connection resources are freed. This fix
 processes all the completion queue before the connection resources are
 freed.
