Subject: [PATCH] libxfs: copy crtime correctly now that it's timespec64

The incore i_mtime and di_crtime are both timespec64 now, which means
that tv_sec is a 64-bit value.  Don't cast that to int32_t when we're
creating an inode, because we'll end up truncating the creation time
incorrectly, should an xfsprogs of this vintage make it to 2039. :P
