losetup: keep -f and <devname> mutually exclusive
losetup tries to blindly use specified device as well as search for
the first free device, the result is:
# losetup /dev/loop1 -f /tmp/tfile_loop1
losetup: /dev/loop1: failed to set up loop device: Invalid argument
fixed version:
# losetup /dev/loop10 -f img
losetup: unexpected arguments
