[jcifs] Bug listing available shares

[Rob Wygand]

Mike,

It *seems* wrong that user X can see user Y's home dir, simply because 
user Y logged into the (our) system first, which is what's happening. 
 From what I understand, you should only ever see your home share.

As for reusing *a*.getCanonicalPath()... yeah, I see that in the 
printing I did that, but that's the only place I did that... all of the 
iterations over the files array use the right SmbFile instance. =)
