Revert "security: tlk_driver: Allow affinity changing"

This reverts commit 7f6caab3a015a82c3f5b8842a5bd461d61d34af1. The
commit introduced a modification that made threads to change
affinity to ensure that the CPU can be changed. However, this
approach was not bullet proof and it was fixed in a separate patch.

Bug 1506585
