Subject: [PATCH v3 2/4] staging: r8188eu: remove unnecessary vaiable in rtw_recv

Return _SUCCESS directly instead of storing it in a variable.
This can prevent cocci warning as follows:

  Unneeded variable: "ret". Return "_SUCCESS" on line 1516

v2 -> v3: rollback to v1 because v2 caused error by kernel test robot
v1 -> v2: made amsdu_to_msdu into void function
