9p: fix bug in attach-per-user
When a new user attached at a directory other than the root, he would end up in the parent directory of the cwd. This was due to a logic error in the code which attaches the user at the mount point and walks back to the cwd. This patch fixes that. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
