    Remove backward compatibility for dmraid without -P option (#788007)
    
    The -P option was first added to dmraid-1.0.0.rc15 released 2006-09-17
    [1].  dmraid-1.0.0.rc16 (a later release) was included in Debian 6 and
    Ubunbu 12.04 LTS.  dmraid-1.0.0.rc13 was included in RedHat/CentOS 5
    however the -P option was back ported into RedHat/CentOS 5.1.
    
    All of these distributions are so old as to be no longer supported and
    yet they provided the dmraid -P option.  Therefore backward
    compatibility for dmraid without the -P option is no longer required.
    So remove it.
