cmsfs-fuse: Fix strip_right() function

Browse Source 
strip_right() strips spaces beginning at the end of the string moving
to the beginning. However, it doesn't check whether it's at beginning
of the array, and would continue reading if the string only contains
spaces.

Fix this by adding the necessary check.
