xfs.h: define XFS_IOC_FREEZE even if FIFREEZE is defined

And the same for XFS_IOC_THAW.  Just because we now have a common
version of the ioctl we still need to provide the old name for it
for anyone using those.

linux.h: include <linux/fs.h>

To reliably prevent the redefinition of struct fsxattr.
