MFC r232749:

Partially undo r228693, by removing NO_WFORMAT.clang in fsdb's Makefile,
and fixing the format string in sbin/fsdb/fsdbutil.c instead.

Note the remark "Work around a problem with format string warnings and
ntohs macros" was actually incorrect.  The DIP(dp, di_nlink) macro
invocation actually returned an int, due to its ternary expression, even
though the di_nlink members of struct ufs1_dinode and struct ufs2_dinode
are both defined as int16_t.
