After commit 
987219ad34a6 ("staging: r8188eu: remove lines from Makefile
that silence build warnings"), clang warns:
drivers/staging/r8188eu/core/rtw_recv.c:499:8: warning: variable
'ether_type' is uninitialized when used here [-Wuninitialized]
                        if (ether_type == eapol_type)
                            ^~~~~~~~~~
drivers/staging/r8188eu/core/rtw_recv.c:458:16: note: initialize the
variable 'ether_type' to silence this warning
        u16     ether_type;
                          ^
                           = 0
1 warning generated.
This if statement sets the exact same assignment as above so just remove
it.
