    bootlist: fix invalid hex number message
    
    In dm_to_part() when kpartx returns no partitions tmajor and tminor are
    empty. As a result the $(printf %d:%d 0x$tmajor 0x$tminor) command
    subsititution reports the following error:
    
    /usr/sbin/bootlist: line 277: printf: 0x: invalid hex number
    
    Fix this by redirecting stderr to /dev/null.
