Alex Deucher 0b492a4c92 drm/amdgpu: cleanup context structure v2
The comment is misleading and incorrect, remove it.

Printing the id is completely meaningless and this practice
can cause a race conditions on command submission.

The flags and hangs fields are completely unused.

Give all fields a common indentation.

v2: remove fpriv reference and unused flags as well, fix debug message.
