btrfs: remove 32bit compat code for VFS inode number

Commit 0b2600f81cefcd ("treewide: change inode->i_ino from unsigned long
to u64") sets the inode number type to u64 unconditionally, so we can
use it directly as there's no difference on 32bit and 64bit platform. We
used to have a copy of the number in our btrfs_inode.

The size of btrfs_inode on 32bit platform is about 688 bytes (after the
change).
