FileManager: Fix asserts on checking properties of symlinks

Browse source 
There were two issues with this code:
- The result of the readlink() call was checked incorrectly for errors.
- This code shouldn't return because otherwise it leaves the GUI buttons
  uninitialized below, causing RefPtr asserts to trigger when the dialog
  tries to access the buttons later on.
