Subject: [PATCH][next] rtw88: coex: fix missing unitialization of variable 'interval'

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

Currently the variable 'interval' is not initialized and is only set
to 1 when oex_stat->bt_418_hid_existi is true.  Fix this by inintializing
variable interval to 0 (which I'm assuming is the intended default).

Addresses-Coverity: ("Uninitalized scalar variable")
Fixes: 5b2e9a35e456 ("rtw88: coex: add feature to enhance HID coexistence performance")
