ALSA: usb-audio: Add Schiit Hel device to mixer map quirk table

commit 22390ce786c59328ccd13c329959dee1e8757487 upstream.

This is a fix equivalent with the upstream commit 22390ce786c5 ("ALSA:
usb-audio: add Schiit Hel device to quirk table"), adapted to the
earlier kernels up to 5.14.y.  It adds the quirk entry with the old
ignore_ctl_error flag to the usbmix_ctl_maps, instead.

The original patch description says:
    The Shciit Hel device responds to the ctl message for the mic capture
    switch with a timeout of -EPIPE:

            usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1
            usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1
            usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1
            usb 7-2.2: cannot get ctl value: req = 0x81, wValue = 0x100, wIndex = 0x1100, type = 1

    This seems safe to ignore as the device works properly with the control
    message quirk, so add it to the quirk table so all is good.
