fix warning: incompatiable argument type of clear_user

hi, Ralf

there are lots of warnings about the macro: clear_user in linux-mips. in linux-2.6.29.3, it will come with errors, so, must be fixed.

the type of the second argument of access_ok should be void __user *, but there is an un-needed (unsigned long) conversion before __cl_addr, so remove the (unsigned long) will fix this problem.

best regards,
Wu Zhangjin
