lockdep: include/linux/lockdep.h - fix warning in net/bluetooth/af_bluetooth.c 



fix this warning:

  net/bluetooth/af_bluetooth.c:60: warning: ‘bt_key_strings’ defined but not used
  net/bluetooth/af_bluetooth.c:71: warning: ‘bt_slock_key_strings’ defined but not used

this is a lockdep macro problem in the !LOCKDEP case.

We cannot convert it to an inline because the macro works on multiple types,
but we can mark the parameter used.

[ also clean up a misaligned tab in sock_lock_init_class_and_name() ]

[ also remove #ifdefs from around af_family_clock_key strings - which
  were certainly added to get rid of the ugly build warnings. ]
