Subject: [PATCH 3/5] partitions/msdos: enumerate also AIX LVM partitions

Graft AIX partitions enumeration in partitions/msdos.c

There is already a AIX disks detection logic in msdos.c.  When an
AIX disk has been found, and if configured to, call the aix partitions
recognizer.  This avoids removal of AIX disks protection from msdos.c,
avoids code duplication, and ensures that AIX partitions enumeration
is called before plain msdos partitions enumeration.
