gpu: nvgpu: Fix build for Linux v6.3

Browse Source 
Upstream Linux commit bc292ab00f6c ("(HEAD) mm: introduce vma->vm_flags
wrapper functions") breaking building the NVGPU driver because the
vm_flags variable is made a const and can no longer be set directly. Fix
the build for Linux v6.3 by using the helper functions for setting the
flags.
