example/nvmf: always return after spdk_subsystem_init

Browse Source 
When the call to spdk_subsystem_init returns synchronously, calling the
callback results in double iterating over states in the state machine.
Returning after calling spdk_subsystem_init allows us to reliably begin
executing after the callback function is executed with no double
execution.
