staging: rtl8723bs: core: make array op_class static const, makes object smaller 



Don't populate the array op_class on the stack but instead make it
static const. Makes the object code smaller by 64 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  93553	   7944	   5056	 106553	  1a039	rtl8723bs/core/rtw_mlme_ext.o

After:
   text	   data	    bss	    dec	    hex	filename
  93425	   8008	   5056	 106489	  19ff9	rtl8723bs/core/rtw_mlme_ext.o

(gcc version 9.2.1, amd64)
