iris: Fix fast-clearing of depth via glClearTex(Sub)Image

Browse source 
If we clear depth only texture via glClearTex(Sub)Image it may cause:
../src/intel/blorp/blorp_genX_exec.h:1554: blorp_emit_surface_states: Assertion `params->depth.enabled || params->stencil.enabled' failed.

due to clear_depth_stencil calling blorp_clear_depth_stencil when
depth is already fast-cleared and there is no stencil.

Fixes piglit test: arb_clear_texture-depth
