2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Oskar Schirmer <[email protected]>

commit a7851ce73b9fdef53f251420e6883cf4f3766534 upstream.

cifs_root_iget allocates full_path through
cifs_build_path_to_root, but fails to kfree it upon
cifs_get_inode_info* failure.

Make all failure exit paths traverse clean up
handling at the end of the function.
