functions: Remove GetObject to check if PLDM is running

In order to check if PLDM is running, the code was subscribing to Name
Owner change and calling GetObject to see if PLDM was running, but PLDM
starts and does not immediately create its Object Manager, therefore
there is a time window when if PLDM starts but hasn't created its Object
Manager, and the openpower service starts, it'll hang forever waiting
for the Name Owner change signal that will not be sent because PLDM
already started.

Instead of calling GetObject, just attempt to run the callback, in this
case setting the bios attribute, and forward the exception if it fails
(due to PLDM not running and the property not existing in D-Bus yet),
so that the openpower service continues to wait. Change the log severity
to informational since setting the bios attribute will fail if PLDM has
not started yet.

Tested: Stopped the PLDM and Entity Manager services and started these
services and the openpower service in various different orders to verify
the openpower service ran when both PLDM and EM had started.
