Subject: [PATCH] shmem: remove unneeded function forward declaration

References: bsc#1190208 (MM functional and performance backports)
Patch-mainline: v5.15-rc1
Git-commit: cdd89d4cb6507f123f6ecbfe51050e9a9844c2ab

The forward declaration for shmem_should_replace_page() and
shmem_replace_page() is unnecessary.  Remove them.
