[PATCH] mwifiex: make arrays static const, makes object smaller

From: Colin Ian King <redacted>

Don't populate the arrays wpa_oui and wps_oui on the stack but
instead them static const. Makes the object code smaller by 63 bytes:

Before:
   text   data  bss     dec    hex filename
  29453   5451   64   34968   8898 .../wireless/marvell/mwifiex/sta_ioctl.o

After:
   text	  data  bss     dec    hex filename
  29356	  5611   64   35031   88d7 ../wireless/marvell/mwifiex/sta_ioctl.o

(gcc version 10.3.0)
