[PATCH] sink-input: Don't assert when removing non-existent volume factor

[arun.raghavan@xxxxxxxxxxxxxxx (Arun Raghavan)]

This makes it easier for users of this API to add/updated a volume
factor by doing a _remove_volume_factor() followed by an
add_volume_factor(), rather than having to either remember whether this
is the first set operation or have an API to query whether a factor has
already been set.
