irqchip/gic-v4: Make sure a VPE is locked when VMAPP is issued
In order to make sure that vpe->col_idx is correctly sampled when a VMAPP
command is issued, the vpe_lock must be held for the VPE. This is now
possible since the introduction of the per-VM vmapp_lock, which can be
taken before vpe_lock in the correct locking order.
