We are printing memory size here, so we should better print it in
decimal instead of hex.

For example: let's suppose we want to print that 256kiB allocation failed.

If we use %zu:
DMA: failed to allocate 256KiB pool for atomic coherent allocation

If we use %zx:
DMA: failed to allocate 100KiB pool for atomic coherent allocation

,which is not really what we want.
