modules: fix modparam async_probe request
commit 4355efbd80482a961cae849281a8ef866e53d55c upstream.
Commit f2411da746985 ("driver-core: add driver module
asynchronous probe support") added async probe support,
in two forms:
* in-kernel driver specification annotation
* generic async_probe module parameter (modprobe foo async_probe)
To support the generic kernel parameter parse_args() was
extended via commit ecc8617053e0 ("module: add extra
argument for parse_params() callback") however commit
failed to f2411da746985 failed to add the required argument.
This causes a crash then whenever async_probe generic
module parameter is used. This was overlooked when the
form in which in-kernel async probe support was reworked
a bit... Fix this as originally intended.
