[PATCH] staging: lustre/lnet: Fix wrong type casting warning generated by sparse

[Niranjan Dighe]

Fixed the following warning reported by sparse about typecasting. A
userspace pointer was being typecasted by simply (char *) which causes
sparse to give the following warning -

warning: cast removes address space of expression

Fixed it by adding __user annotation to the typecasting.
