bnx2: Free IRQ before freeing status block memory
When changing ring size, we free all memory including status block memory. If we're in INTA mode and sharing IRQ, the IRQ handler can be called and it will reference the NULL status block pointer. Because of the lockless design of the IRQ handler, there is no simple way to synchronize and prevent this. So we avoid this problem by freeing the IRQ handler before freeing the status block memory.
