qcacmn: Remove irrelevant qdf_assert_always()

For non-self sta peer (sta_self_peer is set to 0) and in error cases
like (WMA peer create failure), peer->txrx_peer is NULL which
indicates DP peer setup has not happened and therefore there are
no rx cached frames flush. Having a qdf_assert_always() if sta_self_peer
is set to 0 is incorrect. This a valid scenario.

Hence remove the irrelevant qdf_assert_always().
