nfs: no exception without tree
Opening attached file takes much more time if there's no tree (without -V).
In dissect_rpc_chanattrs4() there's nice loop:
for (i = 0; i < rdma_ird_len; i++)
offset = dissect_rpc_uint32(tvb, tree, hf_nfs_rdmachanattrs4, offset);
Which won't be terminated with offset out of bounds when tree == NULL.
(Previously found in bug #7436)
If there's tree but only for display filter (-R tcp), it'll still not throw
exception, but it'll terminate on assert: [Dissector bug, protocol NFS: More
than 1000000 items in the tree -- possible infinite loop]
