[XFS] embededd struct xfs_imap into xfs_inode

Most uses of struct xfs_imap are to map and inode to a buffer.  To avoid
copying around the inode location information we should just embedd a
strcut xfs_imap into the xfs_inode.  To make sure it doesn't bloat an
inode the im_len is changed to a ushort, which is fine as that's what
the users exepect anyway.
