ixgbe, xsk: clean up the resources in ixgbe_xsk_pool_enable error path

In ixgbe_xsk_pool_enable(), if ixgbe_xsk_wakeup() fails,
We should restore the previous state and clean up the
resources. Add the missing clear af_xdp_zc_qps and unmap dma
to fix this bug.

Fixes: d49e286d354e ("ixgbe: add tracking of AF_XDP zero-copy state for each queue pair")
Fixes: 4a9b32f30f80 ("ixgbe: fix potential RX buffer starvation for AF_XDP")
