ixgb: fix bug when freeing resources
It was pointed out by Breno Leitao <leitao@linux.vnet.ibm.com> that
ixgb would crash on PPC when an IOMMU was in use, if change_mtu was
called.
It appears to be a pretty simple issue in the driver that wasn't discovered
because most systems don't run with an IOMMU. The driver needs to only unmap
buffers that are mapped (duh).
