Ignore kIOReturnExclusiveAccess when opening USB interface on macOS 12+

This CL ignores kIOReturnExclusiveAccess result from USBInterfaceOpen
when controlling pan/tilt/zoom and setting appropriate Power Line
frequency for flicker removal. It does so because on macOS 12+, VDCAssistant takes ownership of USB device which makes it so
kIOReturnSuccess is now returned when opening USB interface.
