vulkan: Change mul_mat_id to pad K rather than N (#27925)

The N padding is needed for mul_mat, but not mul_mat_id. For mul_mat_id,
we indirect the row index through a shared memory lookup table which avoids
any OOB row coordinate. But that callback doesn't bounds check K, so we
actually need K padding instead.
