Fix a couple framebuffer related bugs in D3D renderer

Browse Source 
1. A crash in D3D11 renderer when create a texture with flag BGFX_TEXTURE_RT_WRITE_ONLY then override it, bcause m_srv is NULL.
2. In headless mode, RendererContextD3D12::m_swapChain is NULL, clear it resulting a D3D12 debug error
