[PATCH] openbsc[master]: transaction: reject calls from unidentified subscribers

[dexter]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/3127

to look at the new patch set (#4).

transaction: reject calls from unidentified subscribers

A valid subscriber is indespensible when allocating a new
transaction. Return NULL if no subscriber is supplied. This
will cause unidentified subscribers to be rejected.
