Reorganize the dissection code a bit.
Get rid of the global nfserr variable and, instead, have it be local to
interp_reply(). That means one less global variable, which may be good
if any multi-threaded program tries to use libnetdissect in more than
one thread (there are still global variables that would have to be

not fall through, but the other two ("list entry" in various forms,
lines 1741 and 1790) should fall through. The answer lies in the RPC-L
files at [1], [2] and [3] (also line 396), looking at the appropriate IN
or OUT arguments.

Remove a useless warning about the SMB decoder.
In the last couple years it had been proved that any decoder can
potentially have buffer overflows, hence let's not emphasize one of them
more than the others.
