[PATCH] v4l-dev.c: Use 'ret' variable to return release() exit code

[Ezequiel Garcia <elezegarcia@xxxxxxxxx>]

Commit 65d9ff9c85d3c2e06d22aed78efee8404563eff6:
"V4L/DVB (11390): 2-dev.c: return 0 for NULL open and release callbacks",
introduced this bug.

The bug this patch fixes is almost innocuous because nobody
really cares about release() exit code.
