xtensa: fix type conversion in __get_user_size
8-byte access in __get_user_size converts pointer to temporary variable
to the type of original user pointer and then dereferences it, resulting
in the following sparse warning:
sparse: warning: dereference of noderef expression
Instead dereference the original user pointer under the __typeof__ and
add indirection outside.
