[Inspiron 13-7359, Conexant CX20722, Black Mic, Left] Unreliable jack detection

[David Henningsson]

The jack detection of pin 0x19 seems not to be reliable: sometimes when you plug a headphone in, pin 0x19 reports "plugged in" and sometimes it reports "unplugged".

@Raymond, the pcieport errors are unrelated and already reported as bug 1521173
