rbd: small changes
A few very minor changes to the rbd code: - RBD_MAX_OPT_LEN is unused, so get rid of it - Consolidate rbd options definitions - Make rbd_segment_name() return pointer to const char Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Dan Mick <dan.mick@inktank.com> Reviewed-by: Josh Durgin <josh.durgin@inktank.com>
