OPP: Move break out of scoped_guard in dev_pm_opp_xlate_required_opp()

The commit ff9c512041 ("OPP: Use mutex locking guards")
unintentionally made the for loop run longer than required.

scoped_guard() is implemented as a for loop. The break statement now
breaks out out the scoped_guard() and not out of the outer for loop.
The outer loop always iterates to completion.

Fix it.
