[PATCH -next 4/4] drm/radeon/radeon_vm: correct function names in radeon_vm.c

[Yang Yingliang]

Fix the following make W=1 kernel build warnings:

  drivers/gpu/drm/radeon/radeon_vm.c:61: warning: expecting prototype for radeon_vm_num_pde(). Prototype was for radeon_vm_num_pdes() instead
  drivers/gpu/drm/radeon/radeon_vm.c:642: warning: expecting prototype for radeon_vm_update_pdes(). Prototype was for radeon_vm_update_page_directory() instead
