ACPI: don't cond_resched if irq is disabled
commit 8bd108d adds preemption point after each opcode parse, then
a sleeping function called from invalid context bug was founded
during suspend/resume stage. this was fixed in commit abe1dfa by
don't cond_resched when irq_disabled. But recent commit 138d156 changes
the behaviour to don't cond_resched when in_atomic. This makes the
sleeping function called from invalid context bug happen again, which
is reported in http://lkml.org/lkml/2009/12/1/371.
This patch also fixes http://bugzilla.kernel.org/show_bug.cgi?id=14483
