phiopt: Remove candorest variable return instead

After r15-3560-gb081e6c860eb9688d24365d39, the setting of candorest
with the break can just change to a return since this is inside a lambda now.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

	* tree-ssa-phiopt.cc (pass_phiopt::execute): Remove candorest
	and return instead of setting candorest.
