Kernel: Allow Userspace<T> pointers with invalid content

Browse Source 
It's not an error to create a Userspace<T> that points to kernel memory
as the point of Userspace<T> is not to validate the address, but rather
to choose safe overloads that do validation before any data transfer
takes place.

Fixes #4581.
