Subject: [PATCH] [media] rainshadow-cec: ensure exit_loop is initialized

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

exit_loop is not being initialized, so it contains garbage. Ensure it is
initialized to false.

Detected by CoverityScan, CID#1436409 ("Uninitialzed scalar variable")

Fixes: ea6a69defd3311 ("[media] rainshadow-cec: avoid -Wmaybe-uninitialized warning")
Signed-off-by: Colin Ian King <colin.king@...onical.com>
