x86/kgbd: Use NMI_VECTOR not APIC_DM_NMI
[ Upstream commit 2591bc4e8d70b4e1330d327fb7e3921f4e070a51 ]
apic->send_IPI_allbutself() takes a vector number as argument.
APIC_DM_NMI is clearly not a vector number. It's defined to 0x400 which is
outside the vector space.
Use NMI_VECTOR instead as that's what it is intended to be.
