scsi: hisi_sas: Rollback some operations if FLR failed

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8IL6H


CVE: NA

----------------------------------------------------------------------

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.
