Mike Marciniszyn b1151b74ff IB/hfi1: Fix alloc failure with larger txqueuelen 
The following allocation with large txqueuelen will result in the
following warning:

  Call Trace:

For ipoib, the txqueuelen is modified with the module parameter
send_queue_size.

Fix by changing to use kv versions of the same allocator to handle the
large allocations.  The allocation embeds a hdr struct that is dma mapped.
Change that struct to a pointer to a kzalloced struct.
