x86/fpu/debug: Remove unused 'x86_fpu_state' and 'x86_fpu_deactivate_state' tracepoints
Commit:
d1898b733619 ("x86/fpu: Add tracepoints to dump FPU state at key points")
... added the 'x86_fpu_state' and 'x86_fpu_deactivate_state' trace points,
but never used them. Today they are still not used. As they take up
and waste memory, remove them.
