Don't update pools when ingress_lossless_pool is created but the init…

…ialization hasn't finished yet (sonic-net#1685)

Bug:
The buffer pools will be created after a short timer and then won't be
updated until the initialization has finished. This is to avoid
repeatedly updating buffer pools after BUFFER_PG and BUFFER_QUEUE have
been created for each port.
However, when the ingress_lossless_pool is created it will trigger the
buffer pools to be updated for shared headroom pool. If this happens
during intialization, it causes all the buffer pools created after
ingress_lossless_pool won't be created until the initialization has been
done.
Fix:
Don't trigger updating buffer pools when creating ingress_lossless_pool
during intialization.
