[PATCH 5.11 327/329] ext4: fix debug format string warning

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@xxxxxxxx>

commit fcdf3c34b7abdcbb49690c94c7fa6ce224dc9749 upstream.

Using no_printk() for jbd_debug() revealed two warnings:

fs/jbd2/recovery.c: In function 'fc_do_one_pass':
fs/jbd2/recovery.c:256:30: error: format '%d' expects a matching 'int' argument [-Werror=format=]
  256 |                 jbd_debug(3, "Processing fast commit blk with seq %d");
      |                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fs/ext4/fast_commit.c: In function 'ext4_fc_replay_add_range':
fs/ext4/fast_commit.c:1732:30: error: format '%d' expects argument of type 'int', but argument 2 has type 'long unsigned int' [-Werror=format=]
 1732 |                 jbd_debug(1, "Converting from %d to %d %lld",

The first one was added incorrectly, and was also missing a few newlines
in debug output, and the second one happened when the type of an
argument changed.
