bcachefs: bch2_mark_snapshot() now called like other triggers
This fixes a bug where bch2_mark_snapshot() wasn't called for existing
snapshot nodes being updated when child nodes were added.
This led to the data update path thinking the key being updated was for
a snapshot that didn't have children, causing it to fail to insert
whiteouts when splitting existing extents.
