[PATCH] staging: lustre: Fix the warning messages about casting without __user macro

[Shalin Mehta]

From: Shalin Mehta <shalinmeht...@gmail.com>

This issue is showed up while compiling with sparse. The iov_base in struct 
iovec struct explicitly declares that the assigned value should be user space 
pointer with __user macro. Where as here, the __user macro isn't used while 
casting.
