live migration hang if powervc fails to migrate

[Terry Yao]

live migration hang if powervc fails to migrate as powervc driver only wait for the dest host to be different than source host on powervc side. If migration fails on powervc side, powervc will not change the instance host, and the sate will set to "Active".

    Fix infinite loop wait for live-migration completion

    PowerVC will set VM state to "Active" if the live migration failed as
    the source host or dest host is running live migration. With our current
    code, we are looping wait for the migration to be completed until the
    powervc instance's host has been changed. That's definitely wrong..
