[PATCH -next] net: ena: Remove unused variable 'tx_bytes'

From: Chen Zhongjin
Date: Fri Sep 30 2022 - 08:06:38 EST


Reported by Clang [-Wunused-but-set-variable]

'commit 548c4940b9f1 ("net: ena: Implement XDP_TX action")'
This commit introduced the variable 'tx_bytes'. However this variable
is never used by other code except iterates itself, so remove it.
