[PATCH v2 7/8] media: tegra-vde: use 'time_left' variable with wait_for_completion_interruptible_timeout()

[Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>]

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

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

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