staging: rtl8723bs: fix missing unregister_netdev on sdio_alloc_irq failure

In rtw_drv_init(), if rtw_drv_register_netdev() succeeds but sdio_alloc_irq() fails, the error path jumps to free_if1 and calls rtw_sdio_if1_deinit(). However, rtw_sdio_if1_deinit() calls rtw_free_netdev() without a preceding unregister_netdev(), freeing a still-registered netdev but leaving stale sysfs entries behind.
