etnaviv: don't always emit PE_DEPTH_CONFIG on shader changes

Browse source 
Since b29fe26d43 ("etnaviv: rework ZSA into a derived state") the PE
depth config is adjusted by etna_update_zsa() when the shader is changed.
When the PE depth config is actually changing as a result of this
adjustment the ZSA state is dirtied, so there is no need to emit the
state unconditionally when the shader is changed.
