f2fs: use aggressive GC policy during f2fs_disable_checkpoint()
Let's enable GC_URGENT_HIGH mode during f2fs_disable_checkpoint(),
so that we can use SSR allocator for GCed data/node persistence,
it can improve the performance due to it avoiding migration of
data/node locates in selected target segment of SSR allocator.
