btrfs: make array types static const, reduces object code size

Browse source

Don't populate the read-only array types on the stack, instead make
it static const.  Makes the object code smaller by nearly 60 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  90536	   6552	     64	  97152	  17b80	fs/btrfs/ioctl.o

After:
   text	   data	    bss	    dec	    hex	filename
  90414	   6616	     64	  97094	  17b46	fs/btrfs/ioctl.o
