[PATCH 6/7] HID: picoLCD: disable version check during probe

["Bruno Prémont" <bonbons@linux-vserver.org>]

Commit 4ea5454203d991ec85264f64f89ca8855fce69b0
[HID: Fix race condition between driver core and ll-driver] introduced
new locking around proce/remove functions that prevent any report/reply
from hardware to reach driver until it returned from probe.

As such, the ask-reply way to checking picoLCD firmware version during
probe is bound to timeout and let probe fail.

Disabling the check lets driver sucessfully probe again.
