f2fs: fix to abort atomic write only during do_exist()
Commit 7a10f0177e11 ("f2fs: don't give partially written atomic data
from process crash") attempted to drop atomic write data after process
crash, however, f2fs_abort_atomic_write() may be called from noncrash
case, fix it by adding missed PF_EXITING check condition
f2fs_file_flush().
- application crashs
- do_exit
- exit_signals -- sets PF_EXITING
- exit_files
- put_files_struct
- close_files
- filp_close
- flush (f2fs_file_flush)
- check atomic_write_task && PF_EXITING
- f2fs_abort_atomic_write
Fixes: 7a10f0177e11 ("f2fs: don't give partially written atomic data from process crash")
