[PATCH manager] ceph: init: drop deprecated pg_bits parameter

[Kefu Chai <k.chai@proxmox.com>]

The pg_bits parameter was deprecated in commit 9b15baf (PVE 8) after the
underlying Ceph config options (osd_pg_bits / osd_pgp_bits) were removed
from Ceph in v13.0.2.  The implementation was made a no-op at that point,
with a TODO to remove the parameter declaration in PVE 9.

We are now at pve-manager 9.1.6.  The minimum Ceph version supported by
pveceph init is Nautilus (v14), which is already past the point where
these options existed, so the parameter has been a guaranteed no-op on
every cluster PVE 9 can manage.  Remove it along with the adjacent
dead-code comments.
