[PATCH slof] helpers: Fix SLOF_alloc_mem_aligned to meet callers expectation

[Alexey Kardashevskiy <aik@ozlabs.ru>]

Every caller of SLOF_alloc_mem_aligned() assumes the size is the first
argument while it is not.

This switches align and size and fixes random memory corruptions.

This is grep for SLOF_alloc_mem_aligned with this patch applied:

include/helpers.h|27| extern void *SLOF_alloc_mem_aligned(long size, long align);
lib/libveth/veth.c|103| buffer_list = SLOF_alloc_mem_aligned(8192, 4096);
lib/libveth/veth.c|105| rx_queue = SLOF_alloc_mem_aligned(rx_queue_len, 16);
lib/libvirtio/virtio-net.c|101| vq[i].desc = SLOF_alloc_mem_aligned(virtio_vring_size(vq[i].size), 4096);
slof/helpers.c|70| void *SLOF_alloc_mem_aligned(long size, long align)
