sysctl: remove __user qualifier from stack_erasing_sysctl buffer argument
The buffer arg in proc handler functions have been void* (no __user
qualifier) since commit 32927393dc1c ("sysctl: pass kernel pointers to
->proc_handler"). The __user qualifier was erroneously brought back in
commit 0df8bdd5e3b3 ("stackleak: move stack_erasing sysctl to
stackleak.c"). This fixes the error by removing the __user qualifier.
