glusterd: start the brick on a different port

Problem: brick fails to start when the port provided by
glusterd is in use by any other process

Solution: glusterd should check errno set by runner_run()
and if it is set to EADDRINUSE, it should allocate a new
port to the brick and try to start it again.

Previously ret value is checked instead of errno, so the
retry part never executed. Now, we initialize errno to 0
before calling runner framework. and afterwards store the
errno into ret to avoid modification of errno in subsequent
function calls.

fixes: #1101
