NFSv4: Treat ENETUNREACH errors as fatal for state recovery
[ Upstream commit 0af5fb5ed3d2fd9e110c6112271f022b744a849a ]
If a containerised process is killed and causes an ENETUNREACH or
ENETDOWN error to be propagated to the state manager, then mark the
nfs_client as being dead so that we don't loop in functions that are
expecting recovery to succeed.
