[RFC][PATCH 02/27] vfs_rmdir: change if() into goto

[Dave Hansen <haveblue@us.ibm.com>]

We're going to add another condition here in a minute, so
add a goto instead of an if.

There will be a lot of patches like this one.  They may seem
too finely-grained, but I did encounter a couple of bugs where
I botched one of these.  If there is a bug in one, this level
of granularity will really help to track them down with a 
chop-search.
