ceph: use release_pages() directly

Browse Source 
release_pages() has been available to modules since Oct, 2010,
when commit 0be8557bcd ("fuse: use release_pages()") added
EXPORT_SYMBOL(release_pages). However, this ceph code was still
using a workaround.

Remove the workaround, and call release_pages() directly.
