[PATCH 2/3] cifs: consolidate error handling in several functions

[Jeff Layton <jlayton-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

cifs has a lot of complicated functions that have to clean up things on
error, but some of them don't have all of the cleanup code
well-consolidated. Clean up and consolidate error handling in several
functions.

This is in preparation of later patches that will need to put references
to the tcon link container.
