[PATCH] Bluetooth: set reset_resume handler

[Jesse Sung <jesse.sung@canonical.com>]

On some machines, it seems that usb hubs do not get power while
being suspended. We can get something like this in dmesg:
     usb usb2: root hub lost power or was reset

When this is the case, .reset_resume is called instead of .resume.
If .reset_resume is not set, bluetooth modules would stay in an unusable
state because the resume function is not called.
