Luiz Augusto von Dentz 9ae3954dd3 Bluetooth: hci_sync: Fix not checking error on hci_cmd_sync_cancel_sync
commit 1c3366abdbe884be62e5a7502b4db758aa3974c6 upstream.

hci_cmd_sync_cancel_sync shall check the error passed to it since it
will be propagated using req_result which is __u32 it needs to be
properly set to a positive value if it was passed as negative othertise
IS_ERR will not trigger as -(errno) would be converted to a positive
value.
