[PATCH] drm/amdgpu: correct releasing the same sdma fw repeatedly

[Zhang, Hawking]

[AMD Public Use]

Shall we ignore this patch and wait for your latest fixes that remove the asic type check for sdma_v5_2.

I agree with you that should be more reasonable approach.

Regards,
Hawking

Same as sienna_cichlid, dimgrey_cavefish and navy_flounder reuse sdma0 fw for other instances, so free it only once.
