96d32215d4 [SCSI] ESP: Revert ESP_BUS_TIMEOUT back down to 250
This reverts d73f5222a6

The bug that made us increase ESP_BUS_TIMEOUT to 275 turned out to be
a memset bug on 32-bit sparc.

It is better to put this back at the correct timeout value than to
leave it increased when there is no reason for doing so.

d73f5222a6 [SCSI] ESP: Increase ESP_BUS_TIMEOUT to 275.
This matches the original driver's value and seems to be
necessary for some disks on sun4c systems.

cd9ad58d40 [SCSI] SUNESP: Complete driver rewrite to version 2.0
Major features:

1) Tagged queuing support.
2) Will properly negotiate for synchronous transfers even on
   devices that reject the wide negotiation message, such as
   CDROMs
3) Significantly lower kernel stack usage in interrupt
   handler path by elimination of function vector arrays,
   replaced by a top-level switch statement state machine.
4) Uses generic scsi infrastructure as much as possible to
   avoid code duplication.
5) Automatic request of sense data in response to CHECK_CONDITION
6) Portable to other platforms using ESP such as DEC and Sun3
   systems.
