trxcon/scheduler: fix: do not ignore SACCH prims with odd length
Before this patch, prim_dequeue_sacch() used to ignore SACCH primitives
with odd length (e.g. 21, when sender forgot to push 2 octets of L1
SACCH header), so neither they were transmitted, nor rejected.
As a result, they would stay in the Tx queue until a dedicated
connection is released. The only way to notice such problem
was looking at the constantly growing talloc's report.
Instead of ignoring the primitives with odd length and keeping them
in the queue, let's pass them to a logical channel handler, so they
would be dequeued and rejected with a proper logging event.
Also, to simplify further debugging, let's print the final decision
of SACCH prioritization: whether it's a Measurement Report or not.
