Subject: [PATCH 10/13] tracing: deprecate tracing_is_enabled function

Below two commits removed tracing_enabled file, and make function
tracing_is_enable equal to tracing_is_on.

commit(6752ab4): tracing: Deprecate tracing_enabled for tracing_on
commit(0fb9656): tracing: Make tracing_enabled be equal to tracing_on

so we can deprecate old tracing_is_enabled function completely now.

No functionality change.
