Amurthyreddy 89660dbd62 gpu: nvgpu: MISRA 14.4 bitwise operation as boolean
MISRA rule 14.4 doesn't allow the usage of integer types as booleans
in the controlling expression of an if statement or an iteration
statement.

Fix violations where the result of a bitwise operation is used as a
boolean in the controlling expression of if and loop statements.
