[PATCH 11/14] boot: Tidy up logging and naming in vbe_simple

[Simon Glass]

Make sure the log_msg_ret() values are unique so that the log trace is
unambiguous with LOG_ERROR_RETURN. Also avoid reusing the 'node' variable
for two different nodes in bootmeth_vbe_simple_ft_fixup(), since this is
confusing.
