bcachefs: Mark new snapshots earlier in create path

This fixes a null ptr deref when creating new snapshots:
bch2_create_trans() will lookup the subvolume and find the _new_
snapshot in the BCH_CREATE_SUBVOL path that's being created in that
transaction.

We have to call bch2_mark_snapshot() earlier so that it's properly
initialized, instead of leaving it for transaction commit.
