[PATCH] kernel/params: fix a pr_debug(" %p ") in parse_one()

[Jim Cromie]

Inside parse_one(), the core parameter-parsing engine prints the
address of the parameter-set callback function using %p:
pr_debug("handling %s with %p\n", param, params[i].ops->set);

Since the string value of the parameter being parsed (val) is already
available, print the parameter name and its value instead, and avoid
tainting the kernel by exposing a kernel-ptr.
