pruner: remove retry handling + fix early give-up
...
Retry handling is broken since the gRPC changes (wrong error classification).
Will come back at some point, hopefully by merging the replication
driver retry infrastructure.
However, the simpler architecture allows an easy fix for the problem
that the pruner practically gave up on the first error it encountered.

handle changes to placeholder state correctly
...
We assumed that `zfs recv -F FS` would basically replace FS inplace, leaving its children untouched.
That is in fact not the case, it only works if `zfs send -R` is set, which we don't do.
Thus, implement the required functionality manually.
This solves a `zfs recv` error that would occur when a filesystem previously created as placeholder on the receiving side becomes a non-placeholder filesystem (likely due to config change on the sending side):
zfs send pool1/foo@1 | zfs recv -F pool1/bar
cannot receive new filesystem stream:
destination has snapshots (eg. pool1/bar)
must destroy them to overwrite it
