J. Bruce Fields 5ba4a25ab7 nfsd4: disallow ALLOCATE with special stateids 
vfs_fallocate will hit a NULL dereference if the client tries an
ALLOCATE or DEALLOCATE with a special stateid.  Fix that.  (We also
depend on the open to have broken any conflicting leases or delegations
for us.)

(If it turns out we need to allow special stateid's then we could do a
temporary open here in the special-stateid case, as we do for read and
write.  For now I'm assuming it's not necessary.)

Fixes: 95d871f03c "nfsd: Add ALLOCATE support"
