ACPI: s2idle: Log when enabling wakeup IRQ fails
enable_irq_wake() can fail. Previously acpi_s2idle_prepare() silently
ignored it's return code. Based on [1] we should try to continue even in
case of an error, so just log a warning for now.
Discovered when trying to go into s2idle under Xen. This leads to a
system that can't be woken, since xen-pirq currently doesn't support
setting wakeup IRQs [2]. With this you get at least some helpful log
message if you have access to console messages.
