Review Comment:
what if `validatePathCapabilityArgs(path, capability)` in
DfsPathCapablity.hasPathCapablity gives `CommonPathCapabilities.FS_SYMLINKS`.
Now, `FileSystem.areSymlinksEnabled()` can be true or false.
In earlier code, if `FileSystem.areSymlinksEnabled()` is false, we would
retrn from old-line 2213 `cap.get()`. But now, it will go ahead and invoke
`super.hasPathCapability(p, capability);`
