The bug was obswerved while reading code. There are not many users of
addr_mode_nbytes. Anyway, we should update the flash's current address
mode when changing the address mode, fix it. We don't care for now about
the set_4byte_addr_mode(nor, false) from spi_nor_restore(), as it is
used at driver remove and shutdown.
