[PATCH v1] scsi: ufs: core: add is_sys_suspended state before recovery

[HOYOUNG SEO <hy50.seo@samsung.com>]

If a linereset occurs during ufshcd_wl_resume and
a hibern8_exit fail occurs, recovery is performed redundantly
in both the err_handler and the __ufshcd_wl_resume function.
To prevent this redundant recovery, a check for the is_sys_suspended
state has been added to the err_handler.
