mptsas_handle_topo_change() can return without locks held
The expectation of the
mptsas_handle_topo_change() function is that it should always end up always returning with the
mpt->m_mutex held, this is partly why it asserts that it has it. In addition, the calling function does a
mutex_exit() a few lines later. The reality is that whenever this function returns, we need to make sure that we're entered the mutex.
