staging: rtl8723bs: fix missing status update on sdio_alloc_irq() failure

[ Upstream commit 618b4ae ]

The return value of sdio_alloc_irq() was not stored in status.
If sdio_alloc_irq() fails after rtw_drv_register_netdev() succeeds,
status remains _SUCCESS and the error path skips resource cleanup,
while rtw_drv_init() still returns success.

Store the return value of sdio_alloc_irq() in status and reuse the
existing error handling which relies on status.
