Subject: [PATCH] afs: use correct format characters

When compiling with -Wformat, clang warns:

fs/afs/flock.c:632:29: warning: format specifies type 'short' but the argument has type
      'unsigned char' [-Wformat]
        _leave(" = %d [%hd]", ret, fl->fl_type);
                       ~~~         ^~~~~~~~~~~

fl_type is declared as an unsigned char unconditionally in
include/linux/fs.h, so use the correct format characters.
