This patch deals with overlooked situation in patch
d23f72ee501a5bdcc89806eb0ebbba929a36e64d, in which
`irmc_ipmi_succeed` flag is added to deal with iRMC
firmware's IPMI incompatibility introduced at iRMC
firmware version S6 2.00 and later.
That flag is set and updated by `irmc` power_interface
code and rest of iRMC driver code use that flag.
When `ipmitool` is set as power_interface, that flag
is not set nor updated and rest of iRMC driver code
fail to handle IPMI incompatibility correctly.
This patch adds logic to check power_interface to
make iRMC driver properly deal with iRMC firmware's IPMI
incompatibility even when `ipmitool` power_interface
is used.
