Adrian Chadd f7aad20db5 ath: fix ath_buf leak if ath_tx_tag_crypto() returns an error ...

If ath_tx_tag_crypto() returns an error, then ath_tx_normal_setup()
should consume the mbuf and return an error, so the caller knows to
free the ath_buf.  But it wasn't.

This fixes issues I've seen locally where a an AP VAP constantly hits
error conditions (due to other RF/PHY/MAC chipset issues which I haven't
yet figured out) and encryption fails because the station goes away
whilst something's being queued.

Locally tested:

* AR9380, AP mode (2G HT20, 5G HT20, 5G HT40)
