Default re-support special inode

From: Denis Cheng <crquan@gmail.com>

a previous commit removed call to
init_special_inode from inode lookuping, this cause problems as:

# mknod /mnt/gfs2/dev/null c 1 3
# cat /mnt/gfs2/dev/null
cat: /mnt/gfs2/dev/null: Invalid argument

without special inode, GFS2 cannot support char device file,
block device file, fifo pipe, and socket file, lose many important
features as a common file system.

this one line patch re add special inode support.
