Always use TYPE_MODE instead of DECL_MODE for vector field
e034c5c8957 re PR target/78643 (ICE in convert_move, at expr.c:230)
fixed the case where DECL_MODE of a vector field is BLKmode and its
TYPE_MODE is a vector mode because of target attribute. Remove the
BLKmode check for the case where DECL_MODE of a vector field is a vector
mode and its TYPE_MODE isn't a vector mode because of target attribute.

* expr.cc (get_inner_reference): Always use TYPE_MODE for vector
field with vector raw mode.
