vdpa/mlx5: fix wrong MLX5_ADDR_OF struct type in alloc_inout()

Browse Source 
In alloc_inout(), the qpc field offset was computed using
MLX5_ADDR_OF(rst2init_qp_in, ...) in both the INIT2RTR_QP and
RTR2RTS_QP cases. This is a copy-paste error: each case should use
its own input structure type to get the correct qpc offset.

Fix the INIT2RTR_QP case to use MLX5_ADDR_OF(init2rtr_qp_in, ...)
and the RTR2RTS_QP case to use MLX5_ADDR_OF(rtr2rts_qp_in, ...).
