core: thread_enter_user_mode(): avoid leaking register content

Prior to this patch not all registers passed to user mode where assigned
a new value. This allows user mode to see the value of some registers
used by Core. With this patch all general purpose registers available in
user mode are either cleared or assigned a value.
