scsi: ufs: core: Remove the ufshcd_release() in ufshcd_err_handling_prepare()

Browse source 
If ufshcd_err_handler() is called in a suspend/resume situation,
ufs_release() can be called twice and active_reqs end up going negative.
This is because ufshcd_err_handling_prepare() and
ufshcd_err_handling_unprepare() both call ufshcd_release().

Remove superfluous call to ufshcd_release().
