mtd: compat_ioctl cleanup

1) Move the MEMREADOOB/MEMWRITEOOB compat_ioctl wrappers from
fs/compat_ioctl.c into mtdchar.c .  Original request was here:

http://lkml.org/lkml/2009/4/1/295

2) Add missing COMPATIBLE_IOCTL lines, so that mtd-utils does not error
out when running in 64/32 compatibility mode.
