Currently admin doesn't handle adapter removed callbacks, which causes
interfaces AdminPolicySet1 and AdminPolicyStatus1 not being
unregistered, which in turns causes these interfaces can not be
re-registered once adapter is back.
This adds handler for adapter_remove.

tested with following steps
1. rmmod btusb

There are actually some problems with these admin plugin:
https://patchwork.kernel.org/project/bluetooth/patch/20210916223825.276530-1-luiz.dentz@gmail.com/
https://patchwork.kernel.org/project/bluetooth/patch/20210916223825.276530-2-luiz.dentz@gmail.com/
There is also some assumption that there could be only one
policy_data, when in fact there could be multiple btd_adapter in the
system so having admin plugin in a system with multiple adapters might
lead to various problems.
