igb: fix panic while dumping packets on Tx hang with IOMMU
This patch resolves a "BUG: unable to handle kernel paging request at ..."
oops while dumping packet data. The issue occurs with IOMMU enabled due to
the address provided by phys_to_virt().
This patch avoids phys_to_virt() by making using skb->data and the address
of the pages allocated for Rx.
