x86: nmi_32/64.c - use apic_write_around instead of apic_write

Browse Source 
apic_write_around will be expanded to apic_write in 64bit mode
anyway. Only a few CPUs (well, old CPUs to be precise) requires
such an action. In general it should not hurt and could be cleaned
up for apic_write (just in case)
