cifs: Remove {cifs,nfs}_fscache_release_page()

Remove {cifs,nfs}_fscache_release_page() from fs/cifs/fscache.h.  This
functionality got built directly into cifs_release_folio() and will
hopefully be replaced with netfs_release_folio() at some point.

The "nfs_" version is a copy and paste error and should've been altered to
read "cifs_".  That can also be removed.
