ALSA: usb-audio: Fix microphone sound on Opencomm2 Headset

When a Opencomm2 Headset is connected to a Bluetooth USB dongle,
the audio playback functions properly, but the microphone does not work.

In the dmesg logs, there are messages indicating that the init_pitch
function fails when the capture process begins.

The microphone only functions when the ep pitch control is not set.

Toggling the pitch control off bypasses the init_piatch function
and allows the microphone to work.
