Alex Waterman 3966efc2e5 gpu: nvgpu: Give nvgpu_kalloc a less generic name ...

Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary
since the natural free function name for this is nvgpu_kfree() but
that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent
patch).

This API exists becasue not all allocation sizes can be determined
at compile time and in some cases sizes may vary across the system
page size. Thus always using kmalloc() could lead to OOM errors due
to fragmentation. But always using vmalloc() is wastful of memory
for small allocations. This API tries to alleviate those problems.
