selinux: conditional expression type validation was off-by-one
expr_isvalid() in conditional.c was off-by-one and allowed
invalid expression type COND_LAST. However, it is this header file
that needs to be fixed. That way the if-statement's disjunction's
second component reads more naturally, "if expr type is greater than
the last allowed value" ( rather than using ">=" in conditional.c):
if (expr->expr_type <= 0 || expr->expr_type > COND_LAST)
