scsi: be2iscsi: Revert "Fix a theoretical leak in beiscsi_create_eqs()"
My patch caused kernel Oopses and delays in boot. Revert it.
The problem was that I moved the "mem->dma = paddr;" before the call to
be_fill_queue(). But the first thing that the be_fill_queue() function
does is memset the whole struct to zero which overwrites the assignment.
