[PATCH] staging: rtl8723bs: Fix the return value in case of error in 'rtw_wx_read32()'

[Christophe JAILLET]

We return 0 unconditionally in 'rtw_wx_read32()'.
However, 'ret' is set to some error codes in several error handling paths.

Return 'ret' instead to propagate the error code.

Fixes: 554c0a3abf216 ("staging: Add rtl8723bs sdio wifi driver")
