octeontx2-pf: Remove xdp queues on program detach
XDP queues are created/destroyed when a XDP program
is attached/detached. In current driver xdp_queues are not
getting destroyed on program exit due to incorrect xdp_queue
and tot_tx_queue count values.
This patch fixes the issue by setting tot_tx_queue and xdp_queue
count to correct values. It also fixes xdp.data_hard_start address.
