[PATCH -next 2/2] net/rds: Remove unused variable 'total_payload_len'
From: Chen Zhongjin
Date: Fri Sep 30 2022 - 07:56:03 EST
Reported by Clang [-Wunused-but-set-variable]
'commit f9fb69adb6c7 ("RDS: make message size limit compliant with spec")'
This commit introduced the variable 'total_copied'. However this variable
is never used by other code except iterates itself, so remove it.
