pdch: Make sure pending ImmAssRej scheduled for disabled pdch are dropped
When a PDCH TS becomes disabled (eg due to dyn TS being used for a call), we are currently freeing all attached PDCHs in order to avoid further use of it. However, pdch_free_all_tbf() was only freeing TBFs attached to the PDCH, that is, TBFs having a valid TFI assigned. There are some cases where temporary dummy TBFs are created which have no TFI assigned, such as when creating an ImmAssReject. Let's take those into account too, and make sure they are freed.
