Subject: [RFC PATCH v7 10/37] KVM: lapic: Mark apic_find_highest_vector() inline

In preparation for moving apic_find_highest_vector() to
common apic.h header, annotate apic_find_highest_vector() as
inline.

This results (on gcc-13) in slight increase in text size of the
binaries:

Obj-file    Old-bytes    New-bytes
lapic.o     28455        28563
kvm.o       664638       664746
kvm.ko      701907       702015
