There is an unbalanced control regarding to the GATT channel and its
attachid, we have to to update the attach id value by setting it to
zero whenever we detach a GATT channel.

Can you detail how to reproduce the segfault? I want to test on my own setup.

I simply remove a device with a GATT profile, I used thermometer and I
saw that whenever the plugin called to
btd_device_remove_attio_callback, inside this function it was using a
NULL pointer in device->attrib to detach the channel, so I checked it
and I saw that it only is paying attention to the device->attachid
wich was unupdated because it isn't being set to 0 whenever the
channel is detached.

Thanks

Ack.

This bug is also easily reproducible after a local initiated disconnection.
For BLE keep the link up an call test-device disconnect "address"
followed by test-device remove "address"
