IOS: Keep copy of m_devices in USBHost
This gets rid of the ugly direct access to USBScanner::m_devices that
was introduced by the previous commit.
This also fixes a potential thread safety issue.
USB_HIDv4::TriggerDeviceChangeReply loops through m_devices and calls
GetDeviceEntry for each device. If USB_HIDv4::TriggerDeviceChangeReply
is called after a new device is added to m_devices but before hooks are
dispatched, GetDeviceEntry crashes, because the hook that's supposed to
update m_device_ids hasn't run yet. With this commit, this issue can no
longer happen, because USBHost::m_devices_mutex doesn't get unlocked in
between updating m_devices and dispatching the hooks.
