x86/irq: Make irq activate operations symmetric

The recent commit which prevents double activation of interrupts unearthed
interesting code in x86. The code (ab)uses irq_domain_activate_irq() to
reconfigure an already activated interrupt. That trips over the prevention
code now.

Fix it by deactivating the interrupt before activating the new configuration.

	  BNEP (Bluetooth Network Encapsulation Protocol) is Ethernet
	  emulation layer on top of Bluetooth.  BNEP is required for
	  Bluetooth PAN (Personal Area Network).

	  Say Y here to compile BNEP support into the kernel or say M to
	  compile it as module (bnep).

config BT_BNEP_MC_FILTER
	bool "Multicast filter support"
	depends on BT_BNEP
	help
	  This option enables the multicast filter support for BNEP.

config BT_BNEP_PROTO_FILTER
	bool "Protocol filter support"
	depends on BT_BNEP
	help
	  This option enables the protocol filter support for BNEP.
