QStorageInfo: get the label properly if the mounted device is a symlink
This happens for me with LVM:
$ ls -l /dev/mapper/system-root /dev/system/root /dev/disk/by-label/*
lrwxrwxrwx 1 root root 10 Nov 17 22:45 /dev/disk/by-label/system -> ../../dm-1
lrwxrwxrwx 1 root root 7 Nov 17 22:45 /dev/mapper/system-root -> ../dm-1
lrwxrwxrwx 1 root root 7 Nov 17 22:45 /dev/system/root -> ../dm-1
The mounted device according to /etc/mtab (/proc/self/mounts) is
/dev/mapper/system-root.
