[PATCH ipmi-fru-parser] Using new getFRUOjbect() API to fix 'not found in lookup' error message

[OpenBMC Patches]

From: Yi Li <adamliyi at msn.com>

The ipmi-fru-parser calls the dbus method
SystemManager::getObjectFromId('FRU_STR', fru_area_name) for each fru areas
to get the dbus object path of fru area, even if the fru area does not exist.
Also ipmi_validate_fru_area() may be invoked multipul times before
full fru data is parsed. This will generate duplicated error
messages from SystemManager:, e.g:
"ERROR SystemManager: dbus.String(u'INTERNAL_13') not found in lookup".
In this case, "INTERNAL" area does not exists for FRU

For FRUs mananged by BMC (eeprom), ipmi-fru-parser sets the
'present' and 'fault' status of a fru area.
ipmi-fru-parser needs to know whether a fru should be present, based on
whether getObjectFromId() returns valid dbus object path.
So it is expected that getObjectFromId() may be called with
a 'fru_area_name' not defined in Skeleton's ID_LOOKUP table.

In another pull request for skeleton, a new method:
getFRUObject('fru_area_name') is added specially for ipmi-fru-parser.
See PR: https://github.com/openbmc/skeleton/pull/60.

This new method does not report any error message when 'fru_area_name'
not defined in skeleton.
