mm: fix missing page table unmap for stack guard page failure case
commit 5528f9132cf65d4d892bcbc5684c61e7822b21e9 upstream.
.. which didn't show up in my tests because it's a no-op on x86-64 and
most other architectures. But we enter the function with the last-level
page table mapped, and should unmap it at exit.
