drm/nouveau/pm: Prevent overflow in nouveau_perf_init()
While parsing the perf table, there is no check if
the num of entries read from the vbios is less than
the currently allocated number.
In case of a buggy vbios this will cause overwriting
of kernel memory, causing aditional problems.
Add a simple check in order to prevent the case
