Konstantin Belousov 0659df6fad vm_map_protect: allow to set prot and max_prot in one go. 
This prevents a situation where other thread modifies map entries
permissions between setting max_prot, then relocking, then setting prot,
confusing the operation outcome.  E.g. you can get an error that is not
possible if operation is performed atomic.

Also enable setting rwx for max_prot even if map does not allow to set
effective rwx protection.
