[PATCH] sched/core: Fix build paravirt build on arm and arm64

[Mark Brown <broonie@kernel.org>]

Commit 004172bdad64432 (sched/core: Remove unnecessary #include
headers) in current -next removed the inclusion of asm/paravirt.h which
is used to get declarations of paravirt_steal_rq_enabled and
paravirt_steal_clock.  It is implicitly included on but not on arm and
arm64 breaking the build if paravirtualization is used.  Since things
from that header are used directly fix the build by putting the direct
inclusion back.
