[PATCH RT 4/9] preempt: Move preempt_enable_no_resched() to the RT block

[Steven Rostedt]

5.10.78-rt56-rc1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

preempt_enable_no_resched() should point to preempt_enable() on
PREEMPT_RT so nobody is playing any preempt tricks and enables
preemption without checking for the need-resched flag.

This was misplaced in v3.14.0-rt1 und remained unnoticed until now.

Point preempt_enable_no_resched() and preempt_enable() on RT.
