[Samba] Excessive log entries

[Elliott Balsley]

Hello.  I am using Samba 4.8.3 on CentOS 7 and I am seeing a strange error
in the log.

I have usershare max shares = 1 and I have exactly one share defined.
Every time I list shared with *smbclient -L* I see this line in the log:

[2019/09/11
17:41:30.413727,  0] ../source3/param/loadparm.c:3755(load_usershare_shares)
  load_usershare_shares: too many total entries (2) in
directory /usr/local/samba/lib/usershares

$ cat /usr/local/samba/lib/usershares/tank_data
#VERSION 2
path=/tank/data
comment=Comment: /tank/data
usershare_acl=S-1-1-0:F
guest_ok=n
sharename=tank_data

Also, I see the following every time I start the smb service.  I haven't
noticed any real problems but I would like to clean up the log file.
