Subject: [PATCH] NTB: ntb_transport: fix all kernel-doc warnings

Fix all kernel-doc warnings in ntb_transport.c.

The function parameters for ntb_transport_create_queue() changed, so
update them in the kernel-doc comments.
Add a Returns: comment for ntb_transport_register_client_dev().

ntb_transport.c:382: warning: No description found for return value of 'ntb_transport_register_client_dev'
ntb_transport.c:1984: warning: Excess function parameter 'rx_handler' description in 'ntb_transport_create_queue'
ntb_transport.c:1984: warning: Excess function parameter 'tx_handler' description in 'ntb_transport_create_queue'
ntb_transport.c:1984: warning: Excess function parameter 'event_handler' description in 'ntb_transport_create_queue'
