ext4: fix special inode number checks in __ext4_iget()

Browse source 
commit 191ce17876 upstream.

The check for special (reserved) inode number checks in __ext4_iget()
was broken by commit 8a363970d1: ("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.
