media: cx18: make array mapping static, makes object smaller 

Don't populate the array mapping on the stack but instead make it
static. Makes the object code smaller by 79 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  27572	   2096	      0	  29668	   73e4	drivers/media/pci/cx18/cx18-ioctl.o

After:
   text	   data	    bss	    dec	    hex	filename
  27429	   2160	      0	  29589	   7395	drivers/media/pci/cx18/cx18-ioctl.o
