ibmveth: return the error when set_channels cannot add TX queues

If ibmveth_set_channels() fails to allocate a TX long term buffer for a
new queue, it falls back to the old queue count. The successful
netif_set_real_num_tx_queues() call then overwrote rc, so ethtool -L
reported success. This patch saves the allocation error in alloc_rc and
returns it when the fallback succeeds.

[Severity: Low]
This isn't a bug, but should the trailer block carry an Assisted-by tag?

The message body says the bug was found by AI-assisted review. The
trailers only have Fixes: and Signed-off-by:.

Documentation/process/submitting-patches.rst, in "Using Assisted-by:",
says:

  If you used any sort of advanced coding tool in the creation of your
  patch, you need to acknowledge that use by adding an Assisted-by tag.
  Failure to do so may impede the acceptance of your work.

Documentation/process/coding-assistants.rst gives the format:

  Assisted-by: LLM [TOOL1] [TOOL2]

Step 6 of its "Procedure for finding and fixing bugs" section also says
a fix for an AI-found bug should add an Assisted-by tag.

Could an Assisted-by: trailer be added to this commit?
