scsi: pm8001: Fix bogus FW crash for maxcpus=1
According to the comment in check_fw_ready() we should not check the IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers. However we check this very field in process_oq() for processing the highest index interrupt vector. The highest interrupt vector is checked as the FW is programmed to signal fatal errors through this irq. Change that function to not check IOP1_READY for those mentioned controllers, but do check ILA_READY in both cases. The reason I assume that this was not hit earlier was because we always allocated 64 MSI(X), and just did not pass the vector index check in process_oq(), i.e. the handler never ran for vector index 63.
