CIFS: make arrays static const, reduces object code size

Don't populate the read-only arrays types[] on the stack, instead make
them both static const.  Makes the object code smaller by over 200 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
 111503	  37696	    448	 149647	  2488f	fs/cifs/file.o

After:
   text	   data	    bss	    dec	    hex	filename
 111140	  37856	    448	 149444	  247c4	fs/cifs/file.o
