Remove assert in reshape_init_r.

Remove assert in reshape_init_r.

Asserting !BRACE_ENCLOSED_INITIALIZER_P seems pretty pointless, since
that checks for init_list_type_node, and a compound literal won't have
that type, nor will we see that type if we just checked that it's
something else.

	* decl.c (reshape_init_r): Remove assert.
