Removes the need for additional reboot in Lucas

This CL is a fix for the Issue 273264. 

An enumeration of the state table is provided below.

TPM     OK      IA     Behaviour
Clear   Exists  Exists  Not possible, since OK is in statefull partition which cannot be accessed when TPM is cleared.
Clear   !Exists Exists  Reenrollment scenario -> serial key created
Clear   !Exists !Exists Enrollment scenario   -> serial key created
Clear   Exists  !Exists Not possible, since OK is in statefull partition which cannot be accessed when TPM is cleared.
!Clear  Exists  Exists  Regular use scenario -> serial key not created
!Clear  !Exists Exists  Reenrollment scenario -> serial key created
!Clear  Exists  !Exists Not Possible, OK only gets created after we take TPM ownership, which creates IA
!Clear  !Exists !Exists Reenrollment scenario -> serial key created
