[PATCH] Fix dmesg errors about hid2hci not claiming interface before usage.

[Mario Limonciello <mario_limonciello@dell.com>]

[-- Attachment #1.1: Type: text/plain, Size: 420 bytes --]

These errors were caused from trying to detach the kernel driver from
 the interface, which was unnecessary.  A simple usb_claim_interface
 is all that is necessary.  It is however, important to ensure the
 interface claim is successful.
