[ Upstream commit 14bebe3c90b326d2a0df78aed5e9de090c71d878 ]

When flushing out dirty pages, the fact that we may hit fatal errors
is not a reason to stop writeback. Those errors are reported through
fsync(), not through the flush mechanism.

Fixes: a6598813a4c5b ("NFS: Don't write back further requests if there...")
