xen/acpi: Remove the WARN's as they just create noise.
When booting the kernel under machines that do not have P-states we would end up with: ------------[ cut here ]------------ WARNING: at drivers/xen/xen-acpi-processor.c:504 xen_acpi_processor_init+0x286/0 x2e0() Hardware name: ProLiant BL460c G6 Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.39-200.0.3.el5uek #1 Call Trace: [<ffffffff8191d056>] ? xen_acpi_processor_init+0x286/0x2e0 [<ffffffff81068300>] warn_slowpath_common+0x90/0xc0 [<ffffffff8191cdd0>] ? check_acpi_ids+0x1e0/0x1e0 [<ffffffff8106834a>] warn_slowpath_null+0x1a/0x20 [<ffffffff8191d056>] xen_acpi_processor_init+0x286/0x2e0 [<ffffffff8191cdd0>] ? check_acpi_ids+0x1e0/0x1e0 [<ffffffff81002168>] do_one_initcall+0xe8/0x130 .. snip.. Which is OK - the machines do not have P-states, so we fail to register to process the _PXX states. But there is no need to WARN the user of it.
