[PATCH] sh: fix sparse annotation in SH's __get_user_check()

The pointer in get_user() and friends is supposed to be a __user pointer.
But in SH's implementation of __get_user_check(), the pointer is
assigned to a local variable __gu_addr which is lacking the __user
annotation. As consequence, a warning is issued for every of its uses.

So, add the missing __user annotation (this remove ~700 warnings when
using defconfig).
