    Now we've fixed srvstr_pull_req_talloc() this isn't
    strictly needed, but ensuring pointers are initialized
    is best practice to avoid future bugs.

    Robert Morris <rtm at lcs.mit.edu> noticed that in the case
    where srvstr_pull_req_talloc() is being called with
    buffer remaining == 0, we don't NULL out the destination
    pointed which is *always* done in the codepaths inside
    pull_string_talloc(). This prevents a crash in the caller.

    mdssvc: Do an early talloc_free() in _mdssvc_open()
    
    Environment setup:
    When macOS Finder connect to a samba server with 'spotlight = yes',
    macOS would issue mdssvc open (mdssvc.opnum == 0) to samba and it goes
    through api _mdssvc_open().
    
    After applied 578e434a94147dc2d7dbfc006d2ab84807859c1d,
    (this is reported by jaywei at qnap.com)
    this line 'talloc_free(path);' is deleted if _mdssvc_open() normal exit,
    so memory is lazy de-allocate: delayed to
    smbd_tevent_trace_callback() @ smb2_process.c. [1]
    
    Supposed to explicitly free 'path' in _mdssvc_open() @ srv_mdssvc_nt.c[2]
    just like abnormal exit, do not wait for main loop to free 'path' which is
    no longer used, this is more consistent while reading source code.
