ALSA: usb-audio: Fix invalid NULL check in snd_emuusb_set_samplerate()
commit 6de3c9e3f6b3eaf66859e1379b3f35dda781416b upstream.
The quirk function snd_emuusb_set_samplerate() has a NULL check for
the mixer element, but this is useless in the current code. It used
to be a check against mixer->id_elems[unitid] but it was changed later
to the value after mixer_eleme_list_to_info() which is always non-NULL
due to the container_of() usage.
This patch fixes the check before the conversion.
While we're at it, correct a typo in the comment in the function,
too.
