wifi: rtw88: Skip high queue in hci_flush

The flush period may not always intersect with DTIM and when that
happens, an error log "timed out to flush pci TX ring[6]" is shown.
Bypass this since hardware will do proper transmission on the next
DTIM period for broadcast/multicast packets in high queue.
