From: Yihang Li <liyihang9@huawei.com>

In function hisi_sas_controller_prereset(), -ENOSYS (Function not
implemented) should be returned if the driver does not support .soft_reset.
Returns -EPERM (Operation not permitted) if HISI_SAS_RESETTING_BIT is
already be set.

In function _suspend_v3_hw(), returns -EPERM (Operation not permitted) if
HISI_SAS_RESETTING_BIT is already be set.

Fixes: 4522204ab218 ("scsi: hisi_sas: tidy host controller reset function a bit")
