qcacld-3.0: Flush packets in datapath error case

Browse source 
Several packets are sent to firmware in htt_htc_attach_all(), back to
back. However, if one of the latter packets fails to send for some
reason, the previous packets are not flushed. This leads to a number of
leaks under error conditions.

If a packet fails to send in htt_htc_attach_all(), flush the endpoint
before returning failure to the upper layers.
