Subject: [PATCH] rtlwifi: btcoex: remove redundant initialization of variables ant_num and single_ant_path

From: Colin Ian King <colin.king@...onical.com>

The variables ant_num and single_ant_path are being initialized with a
value that is never read and are being updated later with a new value.
The initializations are redundant and can be removed.

Addresses-Coverity: ("Unused value")
