Ryusuke Konishi c0c3d3d3ea nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure ...

commit 723ac75120 upstream.

If creation or finalization of a checkpoint fails due to anomalies in the
checkpoint metadata on disk, a kernel warning is generated.

This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted
with panic_on_warn, does not panic.  A nilfs_error is appropriate here to
handle the abnormal filesystem condition.

This also replaces the detected error codes with an I/O error so that
neither of the internal error codes is returned to callers.
