HID: logitech-dj: Fix error handling in logi_dj_recv_switch_to_dj_mode()
Presently, if a call to logi_dj_recv_send_report() fails, we do
not learn about the error until after sending short
HID_OUTPUT_REPORT with hid_hw_raw_request().
To handle this somewhat unlikely issue, return on error in
logi_dj_recv_send_report() (minding ugly sleep workaround) and
take into account the result of hid_hw_raw_request().
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
