scsi: ufs: core: Remove request tag range checks

The block layer core guarantees that tag numbers are in the expected
range. Hence remove the statements that check this. This patch suppresses
Coverity warnings about left shifts with a negative right hand operand.
The following commit originally introduced request tag range checks:
14497328 ("scsi: ufs: verify command tag validity").
