fs/squashfs: Fix memory leak in sqfs_size_nest()
In case MAX_SYMLINK_NEST is reached while determining the size
on a symlink node, the function returns immediately.
This would not free the resources after the free_strings: label
causing a memory leak.
Set the ret value and just break out of the switch to fix this.
