Kent Overstreet e222d206f2 bcachefs: Fix ec_stripes_read()
Change it to not mark keys that will be overwritten by keys in the
journal - this fixes a bug where we pop an assertion in
bucket_set_stripe() because of a stale pointer - because the stripe that
has the stale pointer has been deleted.

This code could be factored out and used elsewhere, at some point.
