[Skiboot] [PATCH 4/4] ELOG: Remove redundant elog state

[Vasant Hegde]

OPAL gets elog notification from service processor which contains log
information. Once we get notification we start reading log data and
change elog state to ELOG_STATE_FETCHING.

Hence we don't need ELOG_STATE_FETCHED_INFO state. Lets remove this
variable.

Also in some places we have used this state after sending event information
to host. Replace such usage with better state (ELOG_STATE_HOST_INFO).
