Solve "Buffer I/O error on dev loop0p1" error message

This add "losetup" before "kpartx -l" command, otherwise, we encountered
many "Buffer I/O error on dev loop0p1, logical block 104854018,
async page read" in dmesg. But they are seems no harm.

No need to do "losetup -d" after "losetup", because "kpartx -dv"
will do that for us.
