f2fs: fix to tag gcing flag on page during block migration
[ Upstream commit 4961acdd65c956e97c1a000c82d91a8c1cdbe44b ]
It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.
Similar issue was fixed by commit 2d1fe8a86bf5 ("f2fs: fix to tag
gcing flag on page during file defragment").
