fs/afs/: possible cleanups

This patch contains the following possible cleanups:
- make the following needlessly global functions static:
  - rxrpc.c: afs_send_pages()
  - vlocation.c: afs_vlocation_queue_for_updates()
  - write.c: afs_writepages_region()
- make the following needlessly global variables static:
  - mntpt.c: afs_mntpt_expiry_timeout
  - proc.c: afs_vlocation_states[]
  - server.c: afs_server_timeout
  - vlocation.c: afs_vlocation_timeout
  - vlocation.c: afs_vlocation_update_timeout
- #if 0 the following unused function:
  - cell.c: afs_get_cell_maybe()
- #if 0 the following unused variables:
  - callback.c: afs_vnode_update_timeout
  - cmservice.c: struct afs_cm_workqueue
