[PATCH] osmo-bsc[master]: Generate the S_L_INP_TEI_UP signal earlier.

[Stefan Sperling]

Review at  https://gerrit.osmocom.org/6387

Generate the S_L_INP_TEI_UP signal earlier.

The S_L_INP_TEI_UP signal was generated when the first message from a BTS
arrives on the OML/RSL link, rather than when the OML/RSL link comes up.
Instead, generate this signal when the link is brought up, so we
intitialize state regardless of how a particular BTS behaves.

Tested with osmo-bts-virtual and virtphy/mobile programs.
