Silence useless LOOP_GET_STATUS64 warnings

Browse source 
When vold starts up, there are lots of warnings like:

    W vold    : Failed to LOOP_GET_STATUS64 /dev/block/loop30: No such device or address
    W vold    : Failed to LOOP_GET_STATUS64 /dev/block/loop29: No such device or address
    W vold    : Failed to LOOP_GET_STATUS64 /dev/block/loop28: No such device or address

vold is iterating through all loop devices and unbinding the file from
any vold-managed ones.

It's expected that not all loop devices have a file bound to them,
however.  On these, LOOP_GET_STATUS64 fails with ENXIO.

Don't print a warning in such cases.
