[PATCH] ctdb-scripts: Drop use of "smbcontrol winbindd ip-dropped ..."

[Martin Schwenke]

This is unnecessary in Samba >= 4.0 because winbindd monitors IP
address itself and no longer needs to be told when they are dropped.
The smbcontrol commands can hang if a node has recovery mode active
because smbcontrol is unable to connect to the registry.  Therefore,
the smbcontrol commands should be removed.

This can go in as soon as Ralph's netlink socket patch lands.
Hopefully his autobuild will completely successfully in the next
few minutes.  :-)

Please review and push...

peace & happiness,
martin
