drv/intel/fsp2_0/hand_off_block: rework fsp_find_extension_hob_by_guid
Use the new fsp_hob_iterator_get_next_guid_extension function in fsp_find_extension_hob_by_guid instead of iterating through the HOB list in this function. TEST=AMD_FSP_DMI_HOB is still found and the same type 17 DMI info is printed on the console.
