[PATCH] scsi: be2iscsi: Fix a theoretical leak in beiscsi_create_eqs()

[Dan Carpenter]

The be_fill_queue() function can only fail when "eq_vaddress" is NULL
and since it's non-NULL here that means the function call can't fail.
But imagine if it could, then in that situation we would want to store
the "paddr" so that dma memory can be released.
