net: netcp: Fix an error message

BugLink: https://bugs.launchpad.net/bugs/1931896
[ Upstream commit ddb6e00f8413e885ff826e32521cff7924661de0 ]

'ret' is known to be 0 here.
The expected error code is stored in 'tx_pipe->dma_queue', so use it
instead.

While at it, switch from %d to %pe which is more user friendly.
