[PATCH v2 2/2] xfs: hide the XFS_IOC_{ALLOC,FREE}SP* definitions

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Now that we've made these ioctls defunct, move them from xfs_fs.h to
xfs_ioctl.c, which effectively removes them from the publicly supported
ioctl interfaces for XFS.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>

v2: nuke the 32-bit compat definitions too
