[ Upstream commit 2a4a910aa4f0acc428dc8d10227c42e14ed21d10 ]
When parsing a request in nvmet_fc_handle_fcp_rqst() we should not check for invalid target ports; if we do the command is aborted from the fcp layer, causing the host to assume a transport error. Rather we should still forward this request to the nvmet layer, which will then correctly fail the command with an appropriate error status.
