Quiet the following sparse warnings:
warning: cast removes address space of expression
warning: incorrect type in assignment (different address spaces)
expected struct btrfs_ioctl_space_info [noderef] <asn:1>*user_dest
got struct btrfs_ioctl_space_info *<noident>
warning: symbol 'btrfs_ioctl_space_info' was not declared. Should it be static?
