ftrace: replace raw_local_irq_save with local_irq_save
Impact: fix lockdep disabling itself when function tracing is enabled
The raw_local_irq_saves used in ftrace is causing problems with
lockdep. (it thinks the irq flags are out of sync and disables
itself with a warning)
The raw ops here are not needed, and the normal local_irq_save is fine.
