Floss: RTL8852 MSFT support

Because RTL8852 supports only one peer for each monitor, it needs a
special handling to make pattern searching via MSFT work.

When a peer device with the matching pattern is scanned, we need to
split that into its own address monitor. At the same time, we also
report device found. This way we can monitor multiple peer devices.
When the address monitor reports device lost, we cancel the address
monitor and reports device lost to the host as well.
