riscv: Fix up riscv_atomic_assign_expand_fenv [PR94950]

to avoid having the create_tmp_var_raw temporaries without proper DECL_CONTEXT
and not mentioned in local decls.

* config/riscv/riscv-builtins.c (riscv_atomic_assign_expand_fenv): Use
TARGET_EXPR instead of MODIFY_EXPR for first assignment to old_flags.
