mm: change vma_alloc_folio_noprof() macro to inline function

mm: change vma_alloc_folio_noprof() macro to inline function

In a few rare configurations with extra warnings eanbled, the new
drm_pagemap_migrate_populate_ram_pfn() calls vma_alloc_folio_noprof() but
that does not use all the arguments, leading to a harmless warning:

drivers/gpu/drm/drm_pagemap.c: In function 'drm_pagemap_migrate_populate_ram_pfn':
drivers/gpu/drm/drm_pagemap.c:701:63: error: parameter 'addr' set but not used [-Werror=unused-but-set-parameter=]
  701 |                                                 unsigned long addr)
      |                                                 ~~~~~~~~~~~~~~^~~~

Replace the macro with an inline function so the compiler can see how the
argument would be used, but is still able to optimize out the assignments.
