Sami Kiminki f97e7036b1 gpu: nvgpu: sanitize gk20a_vm_alloc_share() ...

Add sanity check for big_page_size parameter to avoid invoking
gk20a_init_vm() with a bogus big page size, potentially hitting a
BUG_ON there. Also, reorganize the code a bit to avoid memory leak in
case of bogus big page size, and properly forward the return value
from gk20a_init_vm().
