Move variable function in lsm_audit.h into SMACK private space

Moved variable function in include/linux/lsm_audit.h into the
smack_audit_data struct since it is never used outside of it.

Also removed setting of function in the COMMON_AUDIT_DATA_INIT
macro because that variable is now private to SMACK.
