Previously, if the OSD cephx-keyring-update init container couldn't
contact the mons, the output redirect would overwrite the on-disk
keyring file with no text, removing the on-disk keyring.
Modify the init container to only overwrite the keyring file when the
ceph command to get the latest key suceeds, to avoid removing the
on-disk key.
