[PATCH] btrfs: return a literal instead of a variable

[Dan Carpenter <dan.carpenter@linaro.org>]

This is just a small clean up, it doesn't change how the code works.
Originally this code had a goto so we needed to set "ret = 0;" but now
it returns directly and so we can simplify it a bit by doing a
"return 0;" and removing the assignment.
