bnx2x: Fix memory leak
There exists an `allocation race' between the CNIC and bnx2x drivers,
in which both drivers allocate the same t2 memory while disregarding a possible
previous allocation.
Additionally, due to the current order of memory releases, some of the
ILT memory in the driver is not released correctly when unloading the driver.
