dyn PDCH: set lchan->state after PDCH DEACT / before PDCH ACT

Do the PDCH DE/ACT before we set the lchan->state to De-/Activation Requested.
It makes more sense semantically to change PDCH mode while the lchan is still
in NONE status. Thus slightly move some invocations:

PDCH ACT: Free the lchan before PDCH activation. Hence remove the lchan_free()
call from the rsl_rx_pdch_act_ack() code path; it used to do the PDCH
activation first and call lchan_free() in the callback.

PDCH DEACT: Set the (TCH) Activation Requested state only within
rsl_chan_activate_lchan(), after the PDCH deact is complete.

Channel allocator: don't pick channels that have a PDCH PENDING flag set, to
avoid using channels that are still in PDCH switchover (despite their state
being NONE).

The lchan_may_change_pdch() sanity checks are becoming a lot simpler.
