[PATCH] block: fix type for printf argument

[PATCH] block: fix type for printf argument

[Ben Dooks]

When making the block-%d id, the type should be %u. Fixes:

block/bio.c:92:62: warning: incorrect type in argument 4 (different types)
block/bio.c:92:62:    expected int
block/bio.c:92:62:    got unsigned int size
