gpu: nvgpu: common: fix MISRA 10.4 violations

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.

Adding "U" at the end of the integer literals to have same type of
operands when an arithmetic operation is performed.

This fix violations where an arithmetic operation is performed on
signed and unsigned int types.

Jira NVGPU-992
