[PATCH] mm/shmem: remove unnecessary restrain unmask of swap gfp flags

[Kairui Song]

From: Kairui Song <kasong@xxxxxxxxxxx>

The comment makes it look like copy-paste leftovers from
shmem_replace_folio. The first try of the swap doesn't always have a
limited zone.

So don't drop the restraint, which should make the GFP more accurate.
