fd leak fix 2009-04-22T07:37:22+00:00 Anand V.

steps:
  - server_finodelk uses req->volume pointer into state->volume
  - finodelk is queued by locks translator
  - c call returns from server_pollin and hdr is FREE'd
  - now state->volname is pointing to FREE'ed region (junk)
  - server_finodelk_cbk calls gf_add_locker
  - gf_add_locker remembers lock with junked path along with fd_ref
  - gf_del_locker from new server_finodelk cannot string match with junked volume thus
    lock is not deleted, hence fd_ref remains as a leak
