mm/fremap.c: fix oops on error path
If find_vma() fails, sys_remap_file_pages() will dereference `vma', which contains NULL. Fix it by checking the pointer. (We could alternatively check for err==0, but this seems more direct) (The vm_flags change is to squish a bogus used-uninitialised warning without adding extra code).
