BUG#27207 Missing parameters in [TCP] seciton cause ndb_Mgmd start failure

This patch fixes

[TCP]
SendBufferMemory= 2M


and things like:

[TCP]
NodeId1=
NodeId2= 12

(which has caused a segfault)

Other tests should be done around here... I'm sure there's a few other
things can cause bad failure modes on incorrect config in some of the
less used parts.
