cifs: fix another memleak, in cifs_root_iget
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.
