glusterd: ignore return code of glusterd_restart_bricks

When GlusterD is restarted on a multi node cluster, while syncing the
global options from other GlusterD, it checks for quorum and based on
which it decides whether to stop/start a brick. However we handle the
return code of this function in which case if we don't want to start any
bricks the ret will be non zero and we will end up failing the import
which is incorrect.

Fix is just to ignore the ret code of glusterd_restart_bricks ()
