media: bdisp: use 'time_left' variable with wait_event_timeout()

There is a confusing pattern in the kernel to use a variable named
'timeout' to store the result of wait_event_timeout() causing
patterns like:

        timeout = wait_event_timeout(...)
        if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the
code self explaining.

Fix to the proper variable type 'long' while here.
