 Log Message:
 Pull up following revision(s) (requested by tsutsui in ticket #317):
        distrib/utils/sysinst/mbr.c: revision 1.91
 Fix regression by my dumb patch in PR/45990.
 sysinst fails with "floating exception" after
 changing MBR partition size in MBR editor menu
 if the target disk doesn't have valid MBR partition
 or has a valid partition 0 whose offset is not 1MB aligned
 (like 63 sectors).
 read_mbr() (which calls get_ptn_alignment()) is called
 before set_bios_geom(), so bhead is not initialized there
 and ptn_alignment could be zero.
 To workaround, explicitly call get_ptn_alignment() again
 in edit_mbr() to update ptn_alignemnt per BIOS geom values.
