ext4: add __user decoration to calls of copy_{from,to}_user()

This quiets the sparse noise:

warning: incorrect type in argument 2 (different address spaces)
   expected void const [noderef] <asn:1>*from
   got struct fstrim_range *<noident>
warning: incorrect type in argument 1 (different address spaces)
   expected void [noderef] <asn:1>*to
   got struct fstrim_range *<noident>
