NFSv3: Ensure that do_proc_get_root() reports errors correctly
commit 086600430493e04b802bee6e5b3ce0458e4eb77f upstream. If the rpc call to NFS3PROC_FSINFO fails, then we need to report that error so that the mount fails. Otherwise we can end up with a superblock with completely unusable values for block sizes, maxfilesize, etc. Reported-by: Yuanming Chen <hikvision_linux@163.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
