ANDROID: userfaultfd: adjust MOVE ioctl mode to confirm bug-fix

Kernel panic was observed in do_swap_page() when invoked on a previously
moved (via MOVE ioctl) page from swap-cache. This was because [1] was not
backported previously and therefore calling page_move_anon_rmap() would
set PG_anon_exclusive flag in the source folio, which shouldn't be done
for a swap-cache folio.
