RFR: 8338693: assert(Atomic::add(&ik->_shared_class_load_count, 1) == 1) failed: shared class loaded more than once [v2]

[Matias Saavedra Silva]

> The test vmTestbase/nsk/sysdict/vm/stress/chain/chain007/chain007.java  occasionally fails due to the number of shared classes being incremented even though the shared class is not loaded. This patch moves the assert to only increment once loading is possible.
