HID: fix suspend crash by moving initializations earlier

commit fde4e2f73208b8f34f123791e39c0cb6bc74b32a upstream.

Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().
