turnip: fix update_stencil_mask

The previous value was not being cleared, resulting in some dynamic stencil
state failures. Fixes these two tests:

dEQP-VK.dynamic_state.ds_state.stencil_params_advanced
dEQP-VK.dynamic_state.ds_state.stencil_params_basic_1

Fixes: 233610f8cf8d8810 ("turnip: refactor draw states and dynamic states")
