Subject: [PATCH v3 2/3] staging: rtl8723au: core: rtw_recv: remove useless codes

There are some useless codes in rtw_free_recvframe23a_queue() and
recvframe_defrag(), so remove them.

Signed-off-by: Geliang Tang <[email protected]>

Changes in v3:
- split it into three patches.
Changes in v2:
- drop the coding style fixing in v1.
