mkimage: fix generation of FIT image

Commit 7a439cadcf3192eb012a2432ca34670b676c74d2 broke generation of SPL
loadable FIT images (CONFIG_SPL_LOAD_FIT).
Fix it by removing the unnecessary storage of expected image type. This was a
left over of the previous implementation. It is not longer necessary since the
mkimage -b switch always has one parameter.
