Subject: [PATCH -next] security: smack: add watch_queue.h header to fix build

From: Randy Dunlap <rdunlap@...radead.org>

Fix build errors when CONFIG_WATCH_QUEUE=y by adding the
appropriate header file.

../security/smack/smack_lsm.c: In function ‘smack_post_notification’:
../security/smack/smack_lsm.c:4384:7: error: dereferencing pointer to incomplete type ‘struct watch_notification’
  if (n->type == WATCH_TYPE_META)
       ^~
../security/smack/smack_lsm.c:4384:17: error: ‘WATCH_TYPE_META’ undeclared (first use in this function); did you mean ‘TCA_PIE_BETA’?
  if (n->type == WATCH_TYPE_META)
                 ^~~~~~~~~~~~~~~
                 TCA_PIE_BETA
