x86: irq: unconditionally define KVM interrupt vectors
Unlike arch/x86/kernel/idt.c, FRED support chose to remove the #ifdefs
from the .c files and concentrate them in the headers, where unused
handlers are #define'd to NULL.
However, the constants for KVM's 3 posted interrupt vectors are still
defined conditionally in irq_vectors.h. In the tree that FRED support was
developed on, this is innocuous because CONFIG_HAVE_KVM was effectively
always set. With the cleanups that recently went into the KVM tree to
remove CONFIG_HAVE_KVM, the conditional became IS_ENABLED(CONFIG_KVM).
This causes a linux-next compilation failure in FRED code, when
CONFIG_KVM=n.
In preparation for the merging of FRED in Linux 6.9, define the interrupt
vector numbers unconditionally.
