Subject: [PATCH] ALSA: ctxfi: Swapped SURROUND-SIDE mute

On Soundblaster X-FI Titenium with emu20k2 the SIDE and SURROUND mute
functions are swapped.
It was checked with 'speaker-test -c 8 -s 3' and (un)mute surround or
'speaker-test -c 8 -s 7' and (un)mute side. The volume seems not
to be affected and works as expected.

Signed-off-by: Sven Eckelmann <sven.eckelmann@....de>

This patch is tested with commit 55fe27f7e2c9d24ce870136bd99ae67b020122d1
which arranges the channels on emu20k2.
