[PATCH next v2 10/11] block: Use a boolean expression instead of max() on booleans

blk_stack_limits() contains:
	t->zoned = max(t->zoned, b->zoned);
These are bool, so can be replaced by bitwise or.
However it generates:
error: comparison of constant '0' with boolean expression is always true [-Werror=bool-compare]
inside the signedness check that max() does unless a '+ 0' is added.
It is a shame the compiler generates this warning for code that will
be optimised away.

Change so that the extra '+ 0' can be removed.
