kernel: modules: netdevices: rtl8365mb: fix mode mask calculation
The RTL8365MB_DIGITAL_INTERFACE_SELECT_MODE_MASK macro was shifting
the 4-bit mask (0xF) by only (_extint % 2) bits instead of
(_extint % 2) * 4. This caused the mask to overlap with the adjacent
nibble when configuring odd-numbered external interfaces, selecting
the wrong bits entirely.
Align the shift calculation with the existing ...MODE_OFFSET macro.
