bts-trx: setup timer once at creation time

The setup is only needed once, so no need to set it every time we want
to schedule it.
Furthermore, it will ease new code introduced in follow-up patches,
which will schedule this timer under some circumstances without need to
send a message at the same time (because re-try of a cmd after a delay
is wanted).

This commit adds an alloc function and an init function to keep
different parts of the code decoupled and avoid exposing more
implementation details between them (like exposing the trx_if timer).
