Add proper "Return:" section in axienet_free_tx_chain() description.
The return value description was present in the function description
but not in the standardized format.
Move the return value description from the main description to a separate
"Return:" section to follow Linux kernel documentation standards.

Fixes below kernel-doc warning:
warning: No description found for return value of 'axienet_free_tx_chain'
