Not handled response in ets:tab2file causing case_clause exception

[sigsergv]

In method ets:tab2file there should be one more case for disk_log:open:

        case disk_log:open([{name, Name}, {file, File}]) of
            {ok, Name} ->
                ok;
            {error, Reason} ->
                throw(Reason)
        end,

disk_log:open could also return term {repaired, ... and this causes unhandled case_clause exception in proper ets:tab2file use.

Unfortunately I cannot provide conditions to reproduce but it could be linked to insuffucient memory.

The file is deleted just before disk_log:open is called:

	_ = file:delete(File),
	case file:read_file_info(File) of
	    {error, enoent} -> ok;
	    _ -> throw(eaccess)
	end,
	Name = make_ref(),
	case disk_log:open([{name, Name}, {file, File}]) of
	    {ok, Name} ->
		ok;
	    {error, Reason} ->
		throw(Reason)
	end,

So I guess getting {repaired, ...} must mean someone else has recreated the file in between (like a racing ets:tab2file). What would the expected behavior be then?
