......................................................................
s1gw: TC_e_rab_setup: complete E-RAB release
The MME originated E-RAB RELEASE procedure includes both:
* [ENB <- MME] E-RAB RELEASE COMMAND, and
* [ENB -> MME] E-RAB RELEASE RESPONSE.
The later was overlooked in a99224c9, so add it.
