Check whether getattr RPC can hold layout MD(RMF_MDT_MD),
in case the client sends some invalid RPC, which can
cause panic on MDT.
Client will retrieve cl_max_md_size/cl_default_md_size
from MDS during mount process, so it will initialize
cl_max_md_size/cl_default_md_size before sending getattr
to MDS.
