f2fs: flush inode if atomic file is aborted

In the Linux kernel, the following vulnerability has been resolved:

f2fs: flush inode if atomic file is aborted

Let's flush the inode being aborted atomic operation to avoid stale dirty
inode during eviction in this call stack:

f2fs_mark_inode_dirty_sync+0x22/0x40 [f2fs]
f2fs_abort_atomic_write+0xc4/0xf0 [f2fs]
f2fs_evict_inode+0x3f/0x690 [f2fs]
? sugov_start+0x140/0x140
evict+0xc3/0x1c0
evict_inodes+0x17b/0x210
generic_shutdown_super+0x32/0x120
kill_block_super+0x21/0x50
deactivate_locked_super+0x31/0x90
cleanup_mnt+0x100/0x160
task_work_run+0x59/0x90
do_exit+0x33b/0xa50
do_group_exit+0x2d/0x80
__x64_sys_exit_group+0x14/0x20
do_syscall_64+0x3b/0x90
entry_SYSCALL_64_after_hwframe+0x63/0xcd

This triggers f2fs_bug_on() in f2fs_evict_inode:
f2fs_bug_on(sbi, is_inode_flag_set(inode, FI_DIRTY_INODE));

This fixes the syzbot report:

loop0: detected capacity change from 0 to 131072
F2FS-fs (loop0): invalid crc value
F2FS-fs (loop0): Found nat_bits in checkpoint
F2FS-fs (loop0): Mounted with checkpoint version = 48b305e4
