ALSA: usb-audio: scarlett2: Fix device hang with ehci-pci

BugLink: https://bugs.launchpad.net/bugs/1931166
commit 764fa6e686e0107c0357a988d193de04cf047583 upstream.

Use usb_rcvctrlpipe() not usb_sndctrlpipe() for USB control input in
the Scarlett Gen 2 mixer driver. This fixes the device hang during
initialisation when used with the ehci-pci host driver.
