[PATCH] smack: fix an compile error in smack_post_notification

[zhong jiang]

I hit the following error when compile the kernel.

security/smack/smack_lsm.c: In function smack_post_notification:
security/smack/smack_lsm.c:4383:7: error: dereferencing pointer to incomplete type struct watch_notification
  if (n->type == WATCH_TYPE_META)
       ^~
security/smack/smack_lsm.c:4383:17: 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
security/smack/smack_lsm.c:4383:17: note: each undeclared identifier is reported only once for each function it appears in
