- do not attempt lock migration if no locks were ever acquired on
  an fd.

- fix fd_lk_ctx_t ref leak during fd migration

- remove spurious fd_unref() (probably added to compensate for
  the fd_ref leak in syncop_open_cbk)

- remove @newfdptr out-param which makes fd ref management really
  tricky (and currently refs were unmanaged for the out-param).
  Instead acquire ref and unref within lock migration function.
