Unused macros reported by [-Wunused-macros].
These macros are introduced to record the bound address of modules.
'80b8bf436990 ("module: Always have struct mod_tree_root")'
This commit has made struct mod_tree_root always exist, which means
we can always referencing mod_tree derectly rather than using this
macro.
So they are useless, remove them for code cleaning.

Yeah, it looks like this removal got lost during a rebase.
Should have been part of 55ce556dbf92 ("module: Remove module_addr_min
and module_addr_max")

a nit, but I would rephrase the changelog a bit...

Commit 80b8bf436990 ("module: Always have struct mod_tree_root") made
"struct mod_tree_root" always present and its members addr_min and
addr_max can be directly accessed.
Macros module_addr_min and module_addr_min are not used anymore, so remove
them.

Thanks all, I've changed the commit message as suggested by Miroslav,
and will queue this up for 6.2.
