[PATCH] dlm: Reuse existing error handling path

From: Christophe JAILLET
Date: Sun Sep 17 2017 - 05:44:03 EST


The error handling path at label 'accept_err' already performs these
'sock_release()' and 'mutex_unlock()' calls. The order is reversed, but
it is not important.
So avoid code duplication and 'goto accept_err'.

While at it, add some missing spaces around a '='.

Instead of returning the magic number -1, we could also propagate the
return value of 'addr_to_nodeid()', that is to say -EEXIST
