ALSA: ice1712: remove redundant assignment to new

The variable new is initialized with a value but it is never read. It is
being re-assigned a new value in every case path in the following switch
statement. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
sound/pci/ice1712/quartet.c:569:8: warning: Although the value stored
to 'new' is used in the enclosing expression, the value is never actually
read from 'new' [deadcode.DeadStores]
