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).
