[PATCH 05/27] rtlwifi: btcoex: 23b 1ant: check if BT high priority packet exist

[Larry Finger]

From: Ping-Ke Shih <pks...@realtek.com>

If there are BT high priority packets, we arrange more time to BT.
To make user experience to  be better, HID and SCO are also seen as
high priority packet exist.
