kernel: mem_domain: Add to current thread should configure immediately.

when a current thread is added to a memory domain the pages/sections
must be configured immediately.
A problem occurs when we add a thread to current and then drop
down to usermode. In such a case memory domain will become active
the next time a swap occurs.
