Subject: [PATCH] greybus/operation: Drop reference when message has been set

In gb_operation_response_send, get an extra reference
before gb_message_send() with this comment "/* Reference will
be dropped when message has been sent. */". Therefore, we
should drop the got reference not only in the error branch,
but also in the complete branch.

Sorry, i mistakenly divided the patch into two commits. What i have sent
is the latest commit which corrected my grammar in the patch.
