xfs: fix the same_inode check in xfs_file_share_range

The VFS i_ino is an unsigned long, while XFS inode numbers are 64-bit wide, so checking i_ino for equality could lead to rate false positives on 32-bit architectures. Just compare the inode pointers themselves to be safe. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
