updated smb-client to make it working again after being bugged for so…

[MarianG]

This change fixes the bug #11296 mentioned by me.
It has to be fixed to use old smb exploit, such as lsa_transnames or trans2open.

Verification

List the steps needed to make sure this thing works

• [x ] Start msfconsole
• [ x] use exploit/linux/samba/lsa_transnames
• [ x] set all options and try to exploit
• [x ] Verify the exploit and other old samba exploits should work again
• Verify The error of unknown method or variable should be gone
• Document the thing and how it works (Example)
