commit 191ce17876c9367819c4b0a25b503c0f6d9054d8 upstream.
The check for special (reserved) inode number checks in __ext4_iget() was broken by commit 8a363970d1dc: ("ext4: avoid declaring fs inconsistent due to invalid file handles"). This was caused by a botched reversal of the sense of the flag now known as EXT4_IGET_SPECIAL (when it was previously named EXT4_IGET_NORMAL). Fix the logic appropriately.
