drm/amdgpu: Convert SDMA instance and index to direct lookup

Instead of searching for the matching SDMA instance inside many of the
SDMA ring vfuncs lets just use the instance number already stored in the
ring and replace the function calls and array walks with direct lookups.

As these helpers are used only from SDMA vfuncs we can remove safely
remove the "is this a SDMA ring" checks as well.

We could add an assert that ring->type queried is AMDGPU_RING_TYPE_SDMA
but as currently there are no debug build only assert macros in this
driver for now I opted not to so the helper can stay a trivial static
inline without polluting the callers with out of line logging.
