Fix firstInstance for vkCmdDraw call

At vktShaderRender. The tests using that common code doesn't seems to
be setting several instances, but the call to cmddraw is setting first
instance to 1. Note that CmdDraw is called on an else path. The if
codepath is already calling CmdDrawIndexed with firstInstance to 0.

Affects:

dEQP-VK.glsl.builtin_var.simple.pointcoord
dEQP-VK.glsl.builtin_var.simple.pointcoord_uniform_vert
dEQP-VK.glsl.builtin_var.simple.pointcoord_uniform_frag

Components: Vulkan
