cso_context: Fix cso_context::sample_mask initial value.

The initial value of cso_context::sample_mask_saved is irrelevant as it
will be overwritten with cso_context::sample_mask in
cso_save_sample_mask.  Therefore it is cso_context::sample_mask that
needs to be properly initialized.

This fixes regressions in blits and mipmap generation after adding
support for sample_mask to llvmpipe.
