[ Upstream commit d43b3a989bc8c06fd4bbb69a7500d180db2d68e8 ]
rpmhpd_aggregate_corner() takes a corner as parameter, but in rpmhpd_power_off() the code requests the level of the first corner instead.
In all (known) current cases the first corner has level 0, so this change should be a nop, but in case that there's a power domain with a non-zero lowest level this makes sure that rpmhpd_power_off() actually requests the lowest level - which is the closest to "power off" we can get.
While touching the code, also skip the unnecessary zero-initialization of "ret".
