This patch should go into 3.5 fixes. The bug was added in the
patches for the 3.5 feature window.

As you can see from the patch I made a mistake. During
development I switched from passing a struct to the size of
the struct, but left the sizeof. This results in us allocating
4 bytes (sizeof(int)) but then calling pci_free_consistent
with the size of the struct.
