scsi: hisi_sas: Rollback some operations if FLR failed
We obtain the semaphore and set HISI_SAS_RESETTING_BIT in
hisi_sas_reset_prepare_v3_hw(), block the scsi host and set
HISI_SAS_REJECT_CMD_BIT in hisi_sas_controller_reset_prepare(), released
them in hisi_sas_controller_reset_done(). However, if the HW reset failure
in FLR results in early return, the semaphore and flag bits will not be
release.
Rollback some operations including clearing flags / releasing semaphore
when FLR is failed.
Fixes: e5ea48014adc ("scsi: hisi_sas: Implement handlers of PCIe FLR for v3 hw")
