Bug in setup-storage and pre-existing vg with no free space

[ivan at trovit.com]

Hello,

I found a problem reinstalling a host using an existing volume group 
name. The regexp used to find out the total space of the vg fails when 
the vg exists and has no free space:

"system" 69280.00 MB [69280.00 MB used / 0 MB free]

This patch changes the regexp to permit a non-float free size (just like 
it permits non-float used size):

Hope it helps, regards
