[XFS] cleanup root inode handling in xfs_fs_fill_super
- rename rootvp to root for clarify - remove useless vn_to_inode call - check is_bad_inode before calling d_alloc_root - use iput instead of VN_RELE in the error case SGI-PV: 976035 SGI-Modid: xfs-linux-melb:xfs-kern:30708a Signed-off-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
