Subject: [PATCH 1/4] [SMB3] Fix warning on uninitialized buftype

Pointed out by coverity analyzer.  resp_buftype is
not initialized in one path which can rarely log
a spurious warning (buf is null so there will
not be a problem with freeing data, but if buf_type
were randomly set to wrong value could log a warning)

Reported by Coverity (CID 1269144)
