Subject: [PATCH] net/tls: Remove redundant initialization of mp

mp is being initialized to log->l_mp but this is never read
as record is overwritten later on. Remove the redundant
initialization.

Cleans up the following clang-analyzer warning:

fs/xfs/xfs_log_recover.c:3543:20: warning: Value stored to 'mp' during
its initialization is never read [clang-analyzer-deadcode.DeadStores].
