[PATCH] Tons of bogus warning messages on attmpt to mount on M18

[Alexey Korolev]

Hi

We faced a lot of warning messages if to mount jffs2 on image generated by mkfs utility.

Warning messages are these:
JFFS2 warning: (696) check_node_data: MTD point returned len too short: 1112 inst
ead of 1816.
JFFS2 warning: (696) check_node_data: MTD point returned len too short: 1276 inst
ead of 2156.
JFFS2 warning: (696) check_node_data: MTD point returned len too short: 1098 inst
ead of 1746.
And many many more.

This patch fixes the issue of warning messages on M18 (Sibley).
