ath9k: fix ready time of the multicast buffer queue
commit 3b3e0efb5c72c4fc940af50b33626b8a78a907dc upstream.
qi->tqi_readyTime is written directly to registers that expect
microseconds as unit instead of TU.
When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so
convert it to microseconds before passing it to ath9k_hw.
This should hopefully fix some Tx DMA issues with buffered multicast
frames in AP mode.
