Remove the header definitions for these ioctls. The just-removed
implementation has allowed callers to read stale disk contents for more
than **21 years** and nobody noticed or complained, which implies a lack
of users aside from exploit programs.

Pull more xfs irix ioctl housecleaning from Darrick Wong:
"Withdraw the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl definitions.
This is the third and final of a series of small pull requests that
perform some long overdue housecleaning of XFS ioctls. This time,
we're withdrawing all variants of the ALLOCSP and FREESP ioctls from
XFS' userspace API. This might be a little premature since we've only
just removed the functionality, but as I pointed out in the last pull
request, nobody (including fstests) noticed that it was broken for 20
years.
In response to the patch, we received a single comment from someone
who stated that they 'augment' the ioctl for their own purposes, but
otherwise acquiesced to the withdrawal. I still want to try to clobber
these old ioctl definitions in 5.17.
So remove the header definitions for these ioctls. The just-removed
implementation has allowed callers to read stale disk contents for
more than **21 years** and nobody noticed or complained, which implies
a lack of users aside from exploit programs"
