xfs: improve xfs_inobt_get_rec prototype
Most callers of xfs_inobt_get_rec need to fill a xfs_inobt_rec_incore_t, and
those who don't yet are fine with a xfs_inobt_rec_incore_t, instead of the
three individual variables, too. So just change xfs_inobt_get_rec to write
the output into a xfs_inobt_rec_incore_t directly.
