Remove invoke_frame_identify, replaced with frame_identify().

This commit fully removes the Frame_Identify invocation and replaces the
calls with frame_identify().
Additionally, because the KCB is special, this commit introduces a new
invocation kcb_identify() which translates the lvaddr in the KCB
capability into the pysical address of the kernel control block.
