xtensa: add missing __user annotations to __{get,put}_user_check
__get_user_check and __put_user_check use temporary pointer but don't mark it as __user, resulting in sparse warnings: sparse: warning: incorrect type in initializer (different address spaces) sparse: expected long *__pu_addr sparse: got long [noderef] <asn:1> *ret sparse: warning: incorrect type in argument 1 (different address spaces) sparse: expected void [noderef] <asn:1> *to sparse: got long *__pu_addr Add __user annotation to temporary pointer in __get_user_check and __put_user_check.
