[PATCH] mm: memcg-v1: account vmpressure event allocations

[Guopeng Zhang]

From: Guopeng Zhang <zhangguopeng@xxxxxxxxxx>

Commit 72797d218b43 ("mm/memcg: v1: account event registrations and drop
world-writable cgroup.event_control") accounted cgroup v1 event
registration allocations with GFP_KERNEL_ACCOUNT, but missed struct
vmpressure_event.

Use GFP_KERNEL_ACCOUNT for this allocation as well.

Fixes: 72797d218b43 ("mm/memcg: v1: account event registrations and drop world-writable cgroup.event_control")
