[PATCH 5.15 011/846] f2fs: avoid EINVAL by SBI_NEED_FSCK when pinning a file

[Greg Kroah-Hartman]

From: Jaegeuk Kim <jaegeuk@xxxxxxxxxx>

commit 19bdba5265624ba6b9d9dd936a0c6ccc167cfe80 upstream.

Android OTA failed due to SBI_NEED_FSCK flag when pinning the file. Let's avoid
it since we can do in-place-updates.
