Subject: [PATCH] checkpatch: add NL_SET_ERR_MSG to 80 column exceptions

NL_SET_ERR_MSG and NL_SET_ERR_MSG_MOD are used to report extended error
responses about failure of a netlink command. These strings often end up
going over the 80-column limit. Just like logging messages, it is
preferred to leave the message all on a single line.

Add these to the exception list so that checkpatch.pl will no longer
complain about the long lines due to use of these macros.
