Pull smb client fix from Steve French:
"Add minor debugging improvement.

The change improves ability to read a network trace to debug problems
on encrypted connections which are very common (e.g. using wireshark
or tcpdump).

That works today with tools like 'smbinfo keys /mnt/file' but requires
passing in a filename on the mount (see e.g. [1]), but it often makes
more sense to just pass in the mount point path (ie a directory not a
filename).

So this fix was needed to debug some types of problems (an obvious
example is on an encrypted connection failing operations on an empty
share or with no files in the root of the directory) - so you can
simply pass in the 'smbinfo keys <mntpoint>' and get the information
that wireshark needs"
