[PATCH 4/4] staging: rtl8723bs: check return value of rtw_wdev_alloc()

[Samasth Norway Ananda]

Add missing error check for rtw_wdev_alloc() in rtw_sdio_if1_init().

rtw_wdev_alloc() can fail with -ENOMEM when wiphy_new() or rtw_zmalloc()
fails, or with other negative error codes when wiphy_register() fails.
Without checking the return value, initialization continues even when
wireless device allocation fails, potentially leaving the adapter in an
inconsistent state.

Jump to the error cleanup path when rtw_wdev_alloc() fails to ensure
proper resource cleanup and prevent use of an incompletely initialized
adapter.
