Fix %x/DWORD printf mismatches in bluetooth

In order to enable clang-cl's printf format string mismatch checking we
need to fix a few dozen existing errors. These are mostly places where
DWORD (unsigned long) is printed with %X - an 'l' is needed. This change
fixes three of these and these files now build cleanly with clang-cl
with PRINTF_FORMAT checking enabled.
