jbd2: don't abort the journal when freeing buffers

mainline inclusion
from mainline-v5.14-rc1
commit 235d6806
category: bugfix
bugzilla: 50788 https://gitee.com/openeuler/kernel/issues/I4DDEL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=235d68069cbd158cb00835d434e9e9accf9a6dd4



---------------------------

Now that we can be sure the journal is aborted once a buffer has failed
to be written back to disk, we can remove the journal abort logic in
jbd2_journal_try_to_free_buffers() which was introduced in
commit c044f3d8 ("jbd2: abort journal if free a async write error
metadata buffer"), because it may cost and propably is not safe.
