Public bug reported:
[Impact]
Use usbcore.quirks kernel parameter let the boot stuck.
[Test]
Without the patch, the usbcore.quirks= doesn't work when usbcore is
builtin. The issue is fixed with the patch.
[Fix]
If the parameter is used at boot, parse the list after the slab is
initialized. When the kcalloc fails, reset the count to 0.
[Regression Potential]
Low. The change limits to quirk parsing, the usbcore behaviour stays the
same.
