usb audio: fix set_parameters read/write concurrency

Do not read the ALSA PCM device configuration when playback
or capture is active.
Do not force ALSA profile update if card and device passed
to out/in_set_parameters() do not change.
Hold the main HAL lock when closing or opening the
ALSA PCM device.

Bug: 15520724.
