[PATCH] drm/tegra: Fix compilation of variadic macro

Commit 43636451db8c ("drm/tegra: Implement job submission part of new
UAPI") added the macro 'SUBMIT_ERR' that in turns makes use of the macro
'__VA_OPT__'. The '__VA_OPT__' macro is not supported by older versions
of GCC and so causes build failures when using older versions of GCC.
Fix this by using the '##__VA_ARGS__' macro instead.
