ALSA: ice1712: Delete unreachable code in aureon_add_controls()
If the check (id != 0x41) fails, then id == 0x41 and
the other check in 'else' branch also
fails: id & 0x0F = 0b01000001 & 0b00001111 = 0b00000001.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
