SMB: Init lanman time and set TZ correctly before calling mktime

Browse source 
This makes a change to the record for smb1-negotiate-response as well.
Times and dates are two 2-byte sections, not three. Switch the parsing
to just use two uint16s, and pass those into the lanman time conversion
function.
