bcache: Correct return value for sysfs attach errors
commit 77fa100f27475d08a569b9d51c17722130f089e7 upstream.
If you encounter any errors in bch_cached_dev_attach it will return
a negative error code. The variable 'v' which stores the result is
unsigned, thus user space sees a very large value returned for bytes
written which can cause incorrect user space behavior. Utilize 1
signed variable to use throughout the function to preserve error return
capability.
