firmware: octeontx2: sfp-info: Update sfp_info_data

commit fab11ccb74b109188b2dca84495c5718c9324a6d from
git@git.assembla.com:cavium/WindRiver.linux.git

This fix is to solve the NULL pointer issue which happens when
trying to unregister the mub_device. Populate the sfp_info_data mdev
member before accessing it in mub_device_unregister().

Fixes: 9317c51441b2 ("sfp-info: Populate sfp_info_data.mdev before using")
