Angus Chen a0e3719e03 vdpa/ifcvf: fix the calculation of queuepair

[ Upstream commit db5db1a00d0816207be3a0166fcb4f523eaf3b52 ]

The q_pair_id to address a queue pair in the lm bar should be
calculated by queue_id / 2 rather than queue_id / nr_vring.

Fixes: 2ddae773c93b ("vDPA/ifcvf: detect and use the onboard number of queues directly")
