[PATCH] staging: rtl8723bs: fix missing unregister_netdev on sdio_alloc_irq failure

[Devansh Soni]

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.
