For PR 2162 - RFS File System - statvfs reports 1 block free

Browse Source 
This is for the RFS file system. The statvfs call reports 1 block free
when the file system is full because it does not account for the superblock
in its calculation of free blocks.
This is a simple fix that adjusts the number of blocks reported to account
for the superblock. We may want to wait for a more complete solution such
as locating the superblock in each group.
