mm/nommu: Fix return type of filemap_map_pages()
If CONFIG_MMU is not set (e.g. m68k/m5272c3_defconfig):
mm/nommu.c:1671:6: error: conflicting types for ‘filemap_map_pages’
1671 | void filemap_map_pages(struct vm_fault *vmf,
| ^~~~~~~~~~~~~~~~~
In file included from mm/nommu.c:20:
./include/linux/mm.h:2578:19: note: previous declaration of ‘filemap_map_pages’ was here
2578 | extern vm_fault_t filemap_map_pages(struct vm_fault *vmf,
| ^~~~~~~~~~~~~~~~~
The signature of filemap_map_pages() was changed, but the nommu
implementation wasn't updated.
