Takashi Iwai 082dcd5166 ALSA: hda: Fix Oops by 9.1 surround channel names 
commit 3b44ec8c5c upstream.

get_line_out_pfx() may trigger an Oops by overflowing the static array
with more than 8 channels.  This was reported for MacBookPro 12,1 with
Cirrus codec.

As a workaround, extend for the 9.1 channels and also fix the
potential Oops by unifying the code paths accessing the same array
with the proper size check.
