losetup: don't ignore EBUSY in losetup when the loop device is given

losetup ignores the EBUSY error.  In the loop fo A_CREATE action, it skips
the error handling when errno = EBUSY.  It's OK for the case where no loop
device is specified, but the error has to be handled when the device is given
explicitly.
