policy_hal: Move global effects to correct output

-With voice playback concurrency handling in place, offload or direct
outputs are force closed if a voice call is on.
-In such scenario, on closeOutput, global effects are moved to
primary output by audioflinger instead of deep buffer output
(mix output).
- When call ends, and playback resumes, movement of effects
from previous output to new output fails.
- Ensure that when a output is closed, effects if present
are moved to mix output, such that when a new output comes up
the effects can be moved from MIX output to the required output.
