Alexandre Ghiti a03ee11b8f riscv: Fix sparse warning about different address spaces 
We did not propagate the __user attribute of the pointers in
__get_kernel_nofault() and __put_kernel_nofault(), which results in
sparse complaining:

>> mm/maccess.c:41:17: sparse: sparse: incorrect type in argument 2 (different address spaces) @@     expected void const [noderef] __user *from @@     got unsigned long long [usertype] * @@
   mm/maccess.c:41:17: sparse:     expected void const [noderef] __user *from
   mm/maccess.c:41:17: sparse:     got unsigned long long [usertype] *

So fix this by correctly casting those pointers.
