sfc: Allocate DMA and event rings using GFP_KERNEL

Browse source

Currently we allocate DMA descriptor rings and event rings using
pci_alloc_consistent() which selects non-blocking behaviour from the
page allocator (GFP_ATOMIC). This is unnecessary, and since we
currently allocate a single contiguous block for each ring (up to 32
pages!) these allocations are likely to fail if there is any
significant memory pressure.  Use dma_alloc_coherent() and GFP_KERNEL
instead.
