spi_flash_mtd_register() can be called several times and each time it
will register the same mtd_info instance like if it was a new one.
The MTD ID allocation gets crazy when that happens, so let's track the
status of the sf_mtd_info object to avoid that.
Fixes: 9fe6d8716e09 ("mtd, spi: Add MTD layer driver")
