Procedure#Entry, check for invalid procedure Id

[Latrasis]

Following on the discussion in #50, #99. #99. Need to include a test where:

1. Create Procedure A into the procedure table.

2. Procedure A is designated as the Entry Procedure during kernel instantiation.

3. Procedure A is also designated a procedure entry capability (type 0x6) that allows it to designate a new entry procedure from the procedure table given an id.

4. If Procedure A tries to invoke the entry capability to assign an new entry procedure with an id that does not exist in the procedure table. The kernel returns an error.
