gpu: nvgpu: Smarter way to check vmalloc address

Browse Source 
In the nvgpu_big_free() function the passed in address is checked
to see what type of address it is: kmalloc or vmalloc. This change
uses the is_vmalloc_addr() instead since this is a much clearer and
easier way to determine if a virtual address should be vfree()ed.
Anything not a vmalloc address is then assumed to be a kmalloc()
address.

rel-28: Note that this code is actually in <nvgpu/kmem.h> on rel-28
so this cherry-pick took that into account.
