APM: uid-device affinity: fix for multiple concurrent apps
Audio mix rules that contain both a match and exclude for a uid
or usage are ignored for routing evaluation. The implementation
of the uid-device affinity caused uid matches and exclusions to
be added to any mixes, causing previously valid mixes to be
discarded in the routing logic.
The fix consists in implementing the uid-device affinity by only
applying uid exclusions on mixes that:
a/ are compatible with the concept (mixes of players that are
render only),
b/ do not route to the selected devices
c/ do not have a uid match rule (such mixes are already exclusive
to the uid to match)
d/ do not already have a uid exclusion for the uid
Fix removeUidDeviceAffinities() that skipped the wrong mixes.
