Logan Gunthorpe 32c0b8f103 nvmet-loop: Flush nvme_delete_wq when removing the port ... [ Upstream commit 86b9a63e595ff03f9d0a7b92b6acc231fecefc29 ] After calling nvme_loop_delete_ctrl(), the controllers will not yet be deleted because nvme_delete_ctrl() only schedules work to do the delete. This means a race can occur if a port is removed but there are still active controllers trying to access that memory. To fix this, flush the nvme_delete_wq before returning from nvme_loop_remove_port() so that any controllers that might be in the process of being deleted won't access a freed port.
