xfs: fix nfs export of 64-bit inodes numbers on 32-bit kernels
The i_ino field in the VFS inode is of type unsigned long and thus can't hold the full 64-bit inode number on 32-bit kernels. We have the full inode number in the XFS inode, so use that one for nfs exports. Note that I've also switched the 32-bit file handles types to it, just to make the code more consistent and copy & paste errors less likely to happen.
