bnx2x: fix null pointer dereference in bnx2x_free_mem_bp()

Browse source

In one of the error path in bnx2x_alloc_mem_bp(), bnx2x_free_mem_bp()
may be called with bp->fp uninitialized. And so, there could be a null
pointer dereference in bnx2x_free_mem_bp(). Fix that by initializing the
fp_array_size after the bp->fp pointer is correctly initialized.
