The rtl8723bs driver manually re-implements list helper functions
and macros in various ways. Replace with existing list helpers.

I'm testing rtl8723bs on a baytrail tablet (Lenovo Ideapad MIIX 300-10IBY)
and applying the tag staging-5.13-rc4, loading r8723bs makes the whole
system freezing while trying to connect to local AP.

Only a power off is allowed.

I found that commit b3cd518c5abd42fbc747ef55a5fdc40bf7bf01c0
(staging: rtl8723bs: Use list iterators and helpers)
introduced the bug.

I'm trying to find out what's wrong with this patch, have you any suggestions?

Some of the iterators needed the _safe variant which I didn't take into account.
I thought that was fixed, but maybe some locations were missed.
