Subject: [PATCH] Reset stencil mask prior to clear.

This fixes a crash on LG ThinQ V60 (LM-V600). From libEGL.so eglSwapBuffers() the libGLESv2_adreno.so causes a segmentation violation (invalid memory reference) without first performing the recommended step of setting the stencil mask back to 0xff.
