revlog: don't say "not found" on internal error...

revlog: don't say "not found" on internal error If index_node() returned NULL, then index_find_node() and and nt_partialmatch() used to return -2 to signal that the node was not found. However, we were passing in a revnum to index_node() that we knew should exist, so the only reason it could return NULL was due to some internal error or perhaps out of memory. Let's not use "not found" for these cases. I suppose we never noticed this because these error never happen in practice. I think there are more places where we should error out instead of reporting that the node was not found, but the cases mentioned above were all I cared about right now (because using the same error code for all failures simplified some future patches).
