Subject: [PATCH] x86/irq: Fix comment on IRQ vector layout
commit f5a3562ec9dd ("x86/irq: Reserve a per CPU IDT vector for posted
MSIs") changed the first system vector from LOCAL_TIMER_VECTOR to
POSTED_MSI_NOTIFICATION_VECTOR. Reflect this change in the vector layout
comment as well.
However, instead of pointing to the specific vector, use the
FIRST_SYSTEM_VECTOR indirection which essentially refers to the same.
This avoids unnecessary modifications to the same comment whenever
additional system vectors get added.
