findFrom(Value begin, int count) causes SIGSEGV when count ~ Integer.MAX_VALUE

[rahulpowar]

Bit of an edge condition and looks like something that should probably be caught closer to aerospike-server but putting it here as we are using the Java client.

When using an LLIST on Aerospike build 3.5.15, issuing the method above with very large values for count causes a SIGSEGV on the server.
