net: ipa: call gsi_evt_ring_rx_update() unconditionally
When an RX transaction completes, we update the trans->len field to
contain the actual number of bytes received. This is done in a loop
in gsi_evt_ring_rx_update().
Change that function so it checks the data transfer direction
recorded in the transaction, and only updates trans->len for RX
transfers.
Then call it unconditionally. This means events for TX endpoints
will run through the loop without otherwise doing anything, but
this will change shortly.
