Function debug_lockdep_rcu_enabled() becomes really hot if several
debug options are enabled together with CONFIG_PROVE_RCU.

This allows to get rid of unneeded invocations.
Function debug_lockdep_rcu_enabled() becomes really hot if several
debug options are enabled together with CONFIG_PROVE_RCU.
Hottest path ends with:
debug_lockdep_rcu_enabled
is_ftrace_trampoline
__kernel_text_address
Here
This allows to get rid of unneeded invocations.
