gpu: nvgpu: Use perf table only VBIOS supports it
We retrieve perf table from VBIOS only if respective HAL op is implemented. Later in code we unconditionally dereference the pointer which can lead to NULL pointer access. Fix by early aborting creation of devinit tables if the perf VBIOS getter is missing.
