Fix spurious errors from kcmio_unix_socket_write
Commit 33634a940166d0b21c3105bab8dcf5550fbbd678 accidentally changed
the return value from kcmio_unix_socket_write to be the result of the
write call. Most commonly this resulted in it returning 8, which led
to many commands failing with "Exec format error".
(cherry picked from commit 3e76ea104cdaf22c4537833b203f8aeed1691f18)
