target: transport_subsystem_check_init cleanups
Remove the now unnecessary extra call to transport_subsystem_check_init() in target_core_register_fabric(), and also merge transport_subsystem_reqmods() directly into transport_subsystem_check_init(). Reported-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
