bounce_buffer->len_aligned is of type "size_t", but on some arches/compilers "size_t" might be an alias to whether "int", "long" or their "signed/unsigned" flavors.
So to make compiler happy we explicitly cast to "int" which is expected in printf for "%d" format.
this fixes following warning: --->--- common/bouncebuf.c: In function ‘addr_aligned’: common/bouncebuf.c:26:3: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t’ [-Wformat=] debug("Unaligned buffer length %d\n", /*(int)*/state->len); ^ --->---

Another way of fixing this would be to use %zu or %zd instead of %d. Although that is a C99 addition so I'm not sure how much people care about really old compilers.
