staging: rtl8188eu: make two arrays static const, makes object smaller

Don't populate two arrays on the stack but instead make them
static const. Makes the object code smaller by 49 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  26821	   5616	      0	  32437	   7eb5	rtl8188eu/core/rtw_ieee80211.o

After:
   text	   data	    bss	    dec	    hex	filename
  26612	   5776	      0	  32388	   7e84	rtl8188eu/core/rtw_ieee80211.o

(gcc version 9.2.1, amd64)
