Martin Schwenke 4b01f54041 ctdb-recoverd: Drop unnecessary and broken code
update_flags() has already updated the recovery master's canonical
node map, based on the flags from each remote node, and pushed out
these flags to all nodes.

If i == j then the node map has already been updated from this remote
node's flags, so simply drop this case.

Although update_flags() has updated flags for all nodes, it did not
update each node map in remote_nodemaps[] to reflect this.  This means
that remote_nodemaps[] may contain inconsistent flags for some nodes
so it should not be used to check consistency when i != j.

Further, a meaningful difference in flags can only really occur if
update_flags() failed.  In that case this code is never reached.

These observations combine to imply that this whole loop should be
dropped.

This leaves potential sub-second inconsistencies due to out-of-band
healthy/unhealthy flag changes pushed via CTDB_SRVID_PUSH_NODE_FLAGS.
These updates could be dropped (takeover run asks each node for
available IPs rather than making centralised decisions based on node
flags) but for now they will be fixed in the next iteration of
main_loop().
