Subject: [PATCH] mpt2sas: Fix for device scan following host reset could get
 stuck in a infinite loop

commit 6241f22ca12a26ee149cbe31b27bac97dbdc8bc4 upstream.

Modified device scan routine so each configuration page read breaks from the
while loop when the ioc_status is not equal to MPI2_IOCSTATUS_SUCCESS.
