scsi: aacraid: Reorder Adapter status check
commit c421530bf848604e97d0785a03b3fe2c62775083 upstream.
The driver currently checks the SELF_TEST_FAILED first and then
KERNEL_PANIC next. Under error conditions(boot code failure) both
SELF_TEST_FAILED and KERNEL_PANIC can be set at the same time.
The driver has the capability to reset the controller on an KERNEL_PANIC,
but not on SELF_TEST_FAILED.
Fixed by first checking KERNEL_PANIC and then the others.
Fixes: e8b12f0fb835223752 ([SCSI] aacraid: Add new code for PMC-Sierra's SRC base controller family)
