PM / Runtime: Don't enable interrupts while running in_interrupt
This patch (as1445) fixes a bug in the runtime PM core left over from
the addition of the no_callbacks flag. If this flag is set then it is
possible for rpm_suspend() to be called in_interrupt, so when
releasing spinlocks it's important not to re-enable interrupts.
To avoid an unnecessary save-and-restore of the interrupt flag, the
patch also inlines a pm_request_idle() call.
This fixes Bugzilla #27482.
(The offending code was added in 2.6.37, so it's not necessary to apply
this to any earlier stable kernels.)
