mptcp: Use struct_group() to avoid cross-field memset()
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() to capture the fields to be reset, so that memset() can be appropriately bounds-checked by the compiler.
