xfs: Fix error return for fallocate() on XFS
Noticed that through glibc fallocate would return 28 rather than -1 and errno = 28 for ENOSPC. The xfs routines uses XFS_ERROR format positive return error codes while the syscalls use negative return codes. Fixup the two cases in xfs_vn_fallocate syscall to convert to negative.
