scsi: ufs: Remove ufshcd_valid_tag()

scsi_add_host() allocates shost->can_queue tags. ufshcd_init() sets
shost->can_queue to hba->nutrs. In other words, we know that tag values
will less than hba->nutrs. Hence remove the checks that verify that
blk_get_request() returns a tag less than hba->nutrs. This check was
introduced by commit 14497328b6a6 ("scsi: ufs: verify command tag
validity").

Keep the tag >= 0 check because it helps to detect use-after-free issues.
