mm/gup.c: mark undo_dev_pagemap as __maybe_unused
[ Upstream commit 790c73690c2bbecb3f6f8becbdb11ddc9bcff8cc ]
Several mips builds generate the following build warning.
mm/gup.c:1788:13: warning: 'undo_dev_pagemap' defined but not used
The function is declared unconditionally but only called from behind
various ifdefs. Mark it __maybe_unused.
