[SCSI] ips: Fix initialization bug with kdump
If I/O is active on the adapter, and an unexpected interrupt is pending
during initialization, the driver blows it's brains out. Since the driver
didn't initiate the I/O, the data in it's internal tables will contain NULL
pointers.
When this condition is detected, a "flush cache and reset" is performed.
The flush cache allows any pending "lazy writes" that the adapter is
processing to complete ( a "must have" for a RAID adapter ) and the reset
puts the adapter back into a known, good state.
