quickscreen: fix EQ enable not working in quickscreen

The EQ enabled setting needs to call into the DSP core when it's
changed but this was only hooked into the EQ menu. The quickscreen
uses option_select_next_val() so those DSP hooks were not getting
called because the setting did not have any callback defined.

It seems this bug was introduced by 362f7a3220 removing the blanket
call to settings_apply(). Other settings might be affected too.
