[SCSI] ips soft lockup during reset/initialization
Resetting the adapter causes the ServeRAID driver to exceed
the max time allowed by the softlock watchdog. Resetting the
hardware can easily require 30 or more seconds. To avoid the
"BUG: soft lockup detected on CPU#0!"
result, this patch replaces the mdelay() calls in the
initialization/reset routines with msleep().
