[PATCH] HID: picolcd_core: Remove setting hdev->claimed before calling hid_hw_start()

Current implementation of hid_hw_start() allows connect_mask to be 0.
Setting hdev->claimed = HID_CLAIMED_INPUT before calling hid_hw_start() is not
necessary. Remove it.

This same change was applied to 3.6 but got lost while applying my
patches on 3.6rc.

I will what else (of 3.5 -> 3.6 changes) might have been lost while applying
driver code split.

Thanks for spotting.
