rbd: eliminate sparse warnings

Fengguang Wu reminded me that there were outstanding sparse reports
in the ceph and rbd code.  This patch fixes these problems in rbd
that lead to those reports:
    - Convert functions that are never referenced externally to have
      static scope.
    - Add a lockdep annotation to rbd_request_fn(), because it
      releases a lock before acquiring it again.

This partially resolves:
