[130/165] ext4: Conditionally define compat ioctl numbers

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

commit 899ad0cea6ad7ff4ba24b16318edbc3cbbe03fad upstream (as of v2.6.34-git13)

It is unnecessary, and in general impossible, to define the compat
ioctl numbers except when building the filesystem with CONFIG_COMPAT
defined.
