dyn pdch: don't PDCH ACT if gprs mode is none

Skip PDCH activation if the GPRS mode is 'none' at:

* TCH/F_PDCH init after OML Enable (dyn_pdch_init())
* after TCH/F_PDCH is released, in TCH/F mode
* in the T3111 error timer callback after a TCH/F_PDCH was released in error
  state

Assert the GPRS mode in rsl_ipacc_pdch_activate() to make sure all callers
check the GPRS mode.

Closes: OS#1765
