If err_handler is performed in the suspend/resume situation, ufs_release
can be called twice and active_reqs valid can be negative.
This is because ufshcd_errhandling_prepare() and
ufshcd_err_handling_unprepare() repeatedly release calls.
Eventually, active_reqs have a value different from the intention.
To prevent this, release duplication processing was removed.
