NFSv4/pnfs: Fix an infinite layoutget loop
Since we can now use a lock stateid or a delegation stateid, that
differs from the context stateid, we need to change the test in
nfs4_layoutget_handle_exception() to take this into account.
This fixes an infinite layoutget loop in the NFS client whereby
it keeps retrying the initial layoutget using the same broken
stateid.
Fixes: 70d2f7b1ea19b ("pNFS: Use the standard I/O stateid when...")
