v3d: fix condition for EZ disabling when stencil on

v3d: fix condition for EZ disabling when stencil on

When stencil is enabled and it isn't non-op, Early-Z must be disabled.

The condition that checks this for stencil[0] is correct, but the one
for stencil[1] is wrong: it uses an "and" instead of "or" condition.

This affects dEQP-GLES3.functional.fragment_ops.interaction.basic_shader.14
