Subject: [PATCH -next] ext4: remove set but not used variable 'es' in ext4_jbd2.c

Fix the following gcc warning:

fs/ext4/ext4_jbd2.c:341:30: warning: variable 'es' set but not used [-Wunused-but-set-variable]
     struct ext4_super_block *es;
                              ^~

Fixes: 2ea2fc775321 ("ext4: save all error info in save_error_info() and drop ext4_set_errno()")
