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