[PATCH] lockdep: address clang -Wformat warning printing for %hd

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Clang doesn't like format strings that truncate a 32-bit
value to something shorter:

kernel/locking/lockdep.c:709:4: error: format specifies type 'short' but the argument has type 'int' [-Werror,-Wformat]

In this case, the warning is a slightly questionable, as it could realize
that both class->wait_type_outer and class->wait_type_inner are in fact
8-bit struct members, even though the result of the ?: operator becomes an
'int'.

However, there is really no point in printing the number as a 16-bit
'short' rather than either an 8-bit or 32-bit number, so just change
it to a normal %d.
