    Revert "Avoid unnecessary automounting in KDiskFreeSpaceInfo::freeSpaceInfo"
    
    This reverts commit 6246e99b43f3d1a9e15d563fbb5e173ed50ba5e5.
    
    It breaks KIO on CIFS mounts as the check for automounts copied over
    from frameworks/kfileitem.cpp isDirectoryMounted() apparently matches
    CIFS as well (and for some weird reason KIO checks for available space
    before trying to copy files).
    
    We'll probably have to return to v1 of the abovementioned commit, i.e.
    checking for "autofs" explicitly. However, more testing is apparently
    necessary to avoid further nasty surprises.
