equalizer: fix switching from passthrough to non-passthrough when parameters change

Browse source 
commit b5bf0294 moved the if(need_new_coefficients) set_passthrough(equ)
after the if(is_passthrough) return FLOW_OK shortcut, so the passthrough
mode would never get updated even if the coefficients change.

Fixes equalizer-test doing .. nothing.
