[PATCH] HID: logitech-dj: Fix check of logi_dj_recv_query_paired_devices()

[YueHaibing]

In delayedwork_callback(), logi_dj_recv_query_paired_devices
may return positive value while success now, so check it
correctly.

Fixes: dbcbabf7da92 ("HID: logitech-dj: fix return value of 
logi_dj_recv_query_hidpp_devices")
