v3.1: svm: remove NativeLoader-owned rent assert (backport of #9574)

[mergify]

Problem

TransactionAccountStateInfo::new() contains a debug assert that a writable account is not owned by NativeLoader. this is overly general, as the condition we actually value is that a reserved account key is not writable

Summary of Changes

remove it. we could check against ReservedAccountKeys here instead but this would require pulling it from Bank through svm. since it is only is debug assert and the condition itself is checked in sanitization, this does not seem necessary
