Subject: [PATCH] net: lio_core: remove redundant assignment to variable tx_done

From: Colin Ian King <colin.king@...onical.com>

The variable tx_done is being assigned with a value that is never read
as the function returns a few statements later.  The assignment is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
