[SCSI] be2iscsi: fix dma free size mismatch regression
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.
