[PATCH v3 03/28] scsi: ufs: Remove superfluous boolean conversions

[Bart Van Assche <bvanassche@acm.org>]

Remove "? true : false" if the preceding expression yields a boolean or if
the result of the expression is assigned to a boolean since in these two
cases the "? true : false" part is superfluous.
