media: qm1d1c0042: fix error return code in qm1d1c0042_init() 

[ Upstream commit fcf8d018bdca0453b8d6359062e6bc1512d04c38 ]

Fix to return a negative error code from the error handling case
instead of 0 in function qm1d1c0042_init(), as done elsewhere
in this function.

Fixes: ab4d14528f ("[media] em28xx: add support for PLEX PX-BCUD (ISDB-S)")
