s3/loadparm: don't mark IPC$ as autoloaded

Browse Source 
A related problem that affects configuration for the hidden IPC$
share. This share is marked a "autoloaded" and such shares are not
reloaded when requested. That resulted in the tcon to IPC$ still using
encrpytion after running the following sequence of changes:

1. stop Samba
2. set [global] smb encrypt = required
3. start Samba
4. remove [global] smb encrypt = required
5. smbcontrol smbd reload-config
6a bin/smbclient -U slow%x //localhost/raw -c quit, or
6b bin/smbclient -U slow%x -mNT1 //localhost/raw -c ls

In 6a the client simply encrypted packets on the IPC$ tcon. In 6b the
client got a tcon failure with NT_STATUS_ACCESS_DENIED, but silently
ignore the error.
