drm: reduce duplicated code in render creation (#247)

Browse source 
initMgpu already does build gl formats so remove the temp creation of
allocator and renderer in onReady() that only built glformats,
also if guard the creation of renderers and allocators to make it less
likely to recreate one that is already existing.
