[qca-nss-drv] removing BUG_ON as it crashes when slub debug is enabled

We hit a BUG_ON when we enable CONFIG_SLUB_DEBUG in
the following code snippet.

	void *kern_addr = kzalloc(PAGE_SIZE, GFP_ATOMIC);
	if (!kern_addr) {
		BUG_ON(!page_count);
		break;
	}
	BUG_ON((long unsigned int)kern_addr % PAGE_SIZE);

We hit the last BUG_ON when slub debug is enabled.
We remove this BUG_ON as we do not require this check
