ACPI: fix mis-merge -- invoke acpi_unlazy_tlb() only on C3 entry

This original patch
http://ussg.iu.edu/hypermail/linux/kernel/0712.2/1451.html
was intending to add acpi_unlazy_tlb() to acpi_idle_enter_bm(),
which is used for C3 entry.

But it was merged incorrectly as commmit

bde6f5f59c2b2b48a7a849c129d5b48838fe77ee
'x86: voluntary leave_mm before entering ACPI C3'

so the call was instead added to acpi_idle_enter_simple()
(which is C2 entry routine), probably due to identical
context in that function.

Move the call back to acpi_idle_enter_bm().
