Coverity: Resolve a CHECKED_RETURN message
Coverity: Resolve a CHECKED_RETURN message

Recent changes to the module seemed to have caused Coverity to find a new
issue regarding the failure to check the return from a sendmsg. The code
doesn't seem to care about the return status, so just added an ignore_value
to keep Coverity quiet.
