EQ IIR: Allow run the EQ in bypass mode when not configured 

This patch changes the behaviour in prepare() such that we do not
return an error if the IIR coefficients have not been set. It's
better to start in bypass mode since this is valid usage for EQ
when transducer EQ or effect does not need to be activated.
