gpu: nvgpu: MISRA 14.4 err/ret/status as boolean

Browse Source 
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 integer variables err, ret, status are used
as booleans in the controlling expression of if and loop statements.
