linux: Take hotplug_lock for scan_devices, hotplug_enumerate and _disconnect

As soon as we've started listening for hp events, hotplug_enumerate and
_disconnect can run, they do test then add / remove operations on the
device list. This can race with scan_devices adding devices, so take
the lock around all 3 to avoid the race.

Also fix the lock not being released in case of linux_start_event_monitor
failure.
