evaluate: Drop dead code from expr_evaluate_mapping()

Since commit 343a51702656a ("src: store expr, not dtype to track data in
sets"), set->data is allocated for object maps in set_evaluate(), all
other map types have set->data initialized by the parser already,
set_evaluate() also checks that.

Drop the confusing check, later in the function set->data is
dereferenced unconditionally.

Fixes: 343a51702656a ("src: store expr, not dtype to track data in sets")
