nilfs2: fix potential kernel bug due to lack of writeback flag waiting
Description

In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential kernel bug due to lack of writeback flag waiting Destructive writes to a block device on which nilfs2 is mounted can cause a kernel bug in the folio/page writeback start routine or writeback end routine (__folio_start_writeback in the log below): kernel BUG at mm/page-writeback.c:3070! Oops: invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI ...

Fix this issue by waiting for ongoing writebacks when putting folios/pages on the backing device into writeback state.
