net: ipa: always use transaction IDs instead of lists
In gsi_channel_trans_complete(), use the completed and pending IDs
to determine whether there are any transactions in completed state.
Similarly, in gsi_channel_trans_cancel_pending(), use the pending
and committed IDs to mark pending transactions cancelled. Rearrange
the logic a bit there for a simpler result.
This removes the only user of list_last_entry_or_null(), so get rid
of that macro.
Remove the temporary warnings added by the previous commit.
