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.
