Audio policy: fix failure to unmute strategy.
When setOutputDevices() is called with a device not supported by the
output profile, checkDeviceMuteStrategies() was not called.
If a strategy was muted by this output because of a previous
device combination, it will never be unmuted.
A typical repro scenario is:
1) music plays over A2DP via offload path
2) incoming call: ringtone plays over speaker + A2DP
=> music is paused by audio focus
3) music manually resumed
=> media strategy is muted because it cannot play over
a2dp + speaker
4) call answered and routed to earpiece
a) offload output is routed to earpiece which is not
supported by offload output profile
=> we fail to unmute media
b) music stream is invalidated because earpiece is
not supported by offload output
=> offload output is closed and we will never unmute media strategy
Fixed by calling checkDeviceMuteStrategies() before exiting in
case of unsupported device.
