HID: uHID: fix excepted report type
When uhid_get_report() or uhid_set_report() are called, they emit on the
char device a UHID_GET_REPORT or UHID_SET_REPORT message. Then, the
protocol says that the user space asnwers with UHID_GET_REPORT_REPLY
or UHID_SET_REPORT_REPLY.
Unfortunatelly, the current code waits for an event of type UHID_GET_REPORT
or UHID_SET_REPORT instead of the reply one.
Add 1 to UHID_GET_REPORT or UHID_SET_REPORT to actually wait for the
reply, and validate the reply.
