Vedashree Vidwans 58f174b29e gpu: nvgpu: fix MISRA errors nvgpu.hal.sync
Rule 2.2 doesn't allow unused variable assignments. The reason is
presence of unused variable assignments may indicate error in program's
logic.
Rule 7.2 requires all unsigned numeric literals to use a "u"/"U" suffix.
Rule 8.3 requires all functions and prototypes to have same parameter
names and type qualifier.
Rule 10.x necessitates operands to have essential type; left and right
operands should be of same width and type.
Rule 12.2 requires right hand operand of shift operator to be within
range 0 to 1 less than width of left hand operand.
This patch fixes above mentioned rules in hal/sync/syncpt_cmdbuf_gv11b.c

Jira NVGPU-3884
