SkiaOutputDeviceVulkan: fix a crash in Reshape()

The crash is because the VulkanSurface::Reshape() could be fail
for some reason, and then swap_chain_ in VulkanSurface could be
nullptr, accessing the nullptr swap_chain causes the crash.
Fix the problem by checking the return value of Reshape call of
VulkanSurface. If it returns false, VulkanSurface::Reshape() will
return false too. So the SkiaOutputSurfaceImplOnGpu will handle
it, and mark context lost.

TODO: investigate why reshape() fail with NVIDIA GPU.
