bcache: Fix an error code in bch_dump_read()

[ Upstream commit d66c9920c0cf984cf99cab5036fd5f3a1b7fba46 ]

The copy_to_user() function returns the number of bytes remaining to be
copied, but the intention here was to return -EFAULT if the copy fails.

Fixes: cafe56359144 ("bcache: A block layer cache")
