sched/rt, net: Use CONFIG_PREEMPTION.patch

BugLink: https://bugs.launchpad.net/bugs/1885932

[ Upstream commit 2da2b32f ]

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT.
Both PREEMPT and PREEMPT_RT require the same functionality which today
depends on CONFIG_PREEMPT.

Update the comment to use CONFIG_PREEMPTION.
