CA-153341: Use local force_state_reset after cross-pool SXM

This fixes cross-pool SXM from a slave. VM.power_state_reset gets
forwarded to the master, which then sees that the VM still appears to be
running on the alive slave, and raises HOST_IS_LIVE.

Calling force_state_reset directly bypasses this check.
