BTS: ignore other RSL messages in function f_TC_paging()

Recent changes [1] to osmo-bts make it periodically send the
RF RESource INDication messages for each transceiver over the
A-bis/RSL.  These messages block the queue of 'RSL_CCHAN' port
and make the paging related test cases fail.  Ignore them.
