Subject: irqchip/gic-v3-its: Fix the incorrect BUG_ON in its_init_vpe_domain()
Patch-mainline: v4.14-rc6
Git-commit: c427a475b6bc9d3304cca04acdec53464f71f24c
References: FATE#323954

The driver probe path hits 'BUG_ON(entries != vpe_proxy.dev->nr_ites)'
on systems where it has VLPI capability, doesn't support direct LPI
feature and boot with a single CPU.

Relax the BUG_ON() condition to fix the issue.
