The logic for the jack detection has not changed since the first
commit for this driver. Remove a duplicate read and remove useless
assignment

sound/soc/codecs/max98090.c:2170:6: style: Variable 'reg' is
reassigned a value before the old one has been
used. [redundantAssignment]
 reg = snd_soc_component_read(component, M98090_REG_JACK_STATUS);
     ^

sound/soc/codecs/max98090.c:2161:7: note: reg is assigned
  reg = snd_soc_component_read(component, M98090_REG_JACK_STATUS);
      ^

sound/soc/codecs/max98090.c:2170:6: note: reg is overwritten
 reg = snd_soc_component_read(component, M98090_REG_JACK_STATUS);
