I see the same with master and earlier smbclient releases. Was thinking
it was due to a malformed request, after the Wireshark dissector shows
the NTtrans Setup section misaligned by one byte (it interprets the
first as padding). However, looking at MS-SMB 2.2.7.2.1 the request
appears to be okay. Probably worth checking against Windows SMB1 client
behaviour...
