[PATCH 4.14 18/89] staging: rtl8723bs: Fix the return value in case of error in rtw_wx_read32()

[ Upstream commit c3e43d8b958bd6849817393483e805d8638a8ab7 ]

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.
