Potential double-free in pulseaudio

Potential double free in Bluez 5 module of PulseAudio could allow a local attacker to leak memory or crash the program. The modargs variable may be freed twice in the fail condition in src/modules/bluetooth/module-bluez5-device.c and src/modules/bluetooth/module-bluez5-device.c. Fixed in 1:8.0-0ubuntu3.14.
