[PATCH] tracing: x86/fpu: Remove unused tracepoints x86_fpu_state and x86_fpu_deactivate_state

[Steven Rostedt]

From: Steven Rostedt (VMware) <rostedt@goodmis.org>

Commit d1898b73 ("x86/fpu: Add tracepoints to dump FPU state at key
points") added trace points x86_fpu_state and x86_fpu_deactivate_state,
but never used them. Today they are still not used. As they take up
and waste memory, remove them.
