[U-Boot] [PATCH] common: fix compiler warning on wrong printf format

[Alexey Brodkin]

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);
   ^
--->---
