mtd: fix different address space noise
In mtd_ioctl MEMGETREGIONINFO the region_user_info pointer ur
is cast in __kernel space. This produces a number of sparse warnings
like:
warning: cast removes address space of expression
warning: incorrect type in initializer (different address spaces)
expected unsigned int const [noderef] <asn:1>*register __p
got unsigned int *<noident>
Since argp is already a void __user * just use it dirrectly without
the cast and make ur a __user *.
