Revert "sched/rt: Provide migrate_disable/enable() inlines"

This reverts commit 56e8949825226341d28dd5156b3d0057684ff669.

The tree contains already the migrate_disable/enable() helpers thus this
stable backport conflicts (b) with the existing definition (compiler
complains with conflicting definition). Thus we don't need this
backported functions and can avoid the conflict by just dropping the
backport.
