Firmware download to the WCN3990 often fails with a 'TLV response size
mismatch' error:
[ 133.064659] Bluetooth: hci0: setting up wcn3990
[ 133.489150] Bluetooth: hci0: QCA controller version 0x02140201
[ 133.495245] Bluetooth: hci0: QCA Downloading qca/crbtfw21.tlv
[ 133.507214] Bluetooth: hci0: QCA TLV response size mismatch
[ 133.513265] Bluetooth: hci0: QCA Failed to download patch (-84)
This is caused by a vendor event 'without command' that is misinterpreted.
Drop the event.

Bluetooth: hci_qca: Rename STATE_<flags> to QCA_<flags>
