LU-16949 lnet: get monitor thread to update ping buffer

Make sure that ping buffer updates requested by o2iblnd and
socklnd are performed by the LNet monitor thread.
Having the LNDs do these updates via an LNet API directly caused a
lock-up due to spinlock acquisition while in an interrupt context
in Centos 7.9 environment.
To avoid LNet trying to update the ping buffer for an LNI which is
still initializing, check that o2iblnd net is fully initialized
(IBLND_INIT_ALL) before requesting the ping buffer update.
