jffs2_scan_make_ino_cache() in scan.c very slow, new improvment

[Joakim Tjernlund]

Is the CRC check needed for the data part(if (ri.csize ....) in
jffs2_scan_inode_node ()
in ? Removing this check halves my already improved mount time :-)

The CRC check of ri.node_crc and rd.node_crc can be removed since it has
already
been checked in jffs2_scan_eraseblock(). OK ?
