bsc: lchan_fsm: Fix invalid duplicated transition
When we enter WAIT_RLL_RTP_RELEASED
(lchan_fsm_wait_rll_rtp_released_onenter), we call lchan_do_release()
which in turn dispatches LCHAN_RTP_EV_RELEASE to lchan_rtp_fsm.c, which
will dispatch back an LCHAN_EV_RTP_RELEASED event, which will be handled
by lchan_fsm_wait_rll_rtp_released(), which will change state to
WAIT_BEFORE_RF_RELEASE. When going back the stack (return), we are still
in lchan_fsm_wait_rll_rtp_released_onenter() which again triggers a
change state to WAIT_BEFORE_RF_RELEASE because it checks same conditions
than first one.
