ALSA: usb: Add Plantronics C320-M USB ctrl msg delay quirk

BugLink: https://bugs.launchpad.net/bugs/1920246
commit fc7c5c208eb7bc2df3a9f4234f14eca250001cb6 upstream.

The microphone in the Plantronics C320-M headset will randomly
fail to initialize properly, at least when using Microsoft Teams.
Introducing a 20ms delay on the control messages appears to
resolve the issue.
