Terje Bergstrom f37f4e27e3 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.
