Subject: [PATCH] osd: increase default hard pg limit

The hard limit was too easy to hit during failure cases, especially
due to mismatched device sizes causing high variance in pgs/osd.

Fixes: https://tracker.ceph.com/issues/24243
Signed-off-by: Josh Durgin <jdurgin@redhat.com>
(cherry picked from commit dfdedce89521f89046fb13287d9fdd683c91e242)
