ARM: 8551/2: DMA: Fix kzalloc flags in __dma_alloc

Commit 19e6e5e5392b ("ARM: 8547/1: dma-mapping: store buffer
information") allocates a structure meant for internal buffer management
with the GFP flags of the buffer itself. This can trigger the following
safeguard in the slab/slub allocator:

	if (unlikely(flags & GFP_SLAB_BUG_MASK)) {
		pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK);
		BUG();
	}

Fix this by filtering the flags that make the slab allocator unhappy.
