i2c: i2c-boardinfo: fix memory leaks on devinfo
Currently when an error occurs devinfo is still allocated but is
unused when the error exit paths break out of the for-loop. Fix
this by kfree'ing devinfo to avoid the leak.
Detected by CoverityScan, CID#1416590 ("Resource Leak")
Fixes: 4124c4eba402 ("i2c: allow attaching IRQ resources to i2c_board_info")
Fixes: 0daaf99d8424 ("i2c: copy device properties when using i2c_register_board_info()")
