gpu: nvgpu: Fix big_pages logic in nvgpu_vm_init
Fix the way big_pages is handled in nvgpu_vm_init(). Prior to this
patch big_pages could wind up being true even if disable_bigpages is
set in the mm struct. Clearly this is wrong.
The logic is now simplified a little bit and makes it so that if the
disable_bigpages field is set then the resulting VM created by
nvgpu_vm_init() has only one user area (no need for a second LP user
area) and the big_pages field for the VM is set to false.
