#1168755 — [PATCH v4 6/8] extcon: arizona: Ensure variables are set for headphone detection

The detecting flag really refers to the microphone detection stage and
as such should be cleared before arizona_identify_headphones is called.
Also the mic flag should be set before identify headphones is called as
well.
