gpu: nvgpu: WAR unlikely() bug in CLANG

CLANG, when compiling regops_gk20a.c sees the following warning:

../drivers/gpu/nvgpu/gk20a/regops_gk20a.c:464:30: error: equality comparison with extraneous parentheses [-Werror,-Wparentheses-equality]
if (unlikely(skip_read_lo == false)) {
             ~~~~~~~~~~~~~^~~~~~~~
../drivers/gpu/nvgpu/gk20a/regops_gk20a.c:464:30: note: remove extraneous parentheses around the comparison to silence this warning
if (unlikely(skip_read_lo == false)) {
            ~             ^       ~

../drivers/gpu/nvgpu/gk20a/regops_gk20a.c:464:30: note: use '=' to turn this equality comparison into an assignment
if (unlikely(skip_read_lo == false)) {
                          ^~
                          =
1 error generated.

But this obviously is fine. However, it's simple enough to work around
by just deleting the unlikely() call. We don't do anything with that
anyway.
