s390/cio: remove uevent suppress from cio driver

commit fa1a8c23eb7d ("s390: cio: Delay uevents for subchannels")
introduced suppression of uevents for a subchannel until after it is
clear that the subchannel would not be unregistered again
immediately. This was done to avoid uevents being generated for I/O
subchannels with no valid device, which can happen on LPAR.

However, this also has some drawbacks: All subchannel drivers need to
manually remove the uevent suppression and generate an ADD uevent as
soon as they are sure that the subchannel will stay around. This misses
out on all uevents that are not the initial ADD uevent that would be
generated while uevents are suppressed; for example, all subchannels
were missing the BIND uevent.

As uevents being generated even for I/O subchannels without an
operational device turned out to be not as bad as missing uevents and
complicating the code flow, let's remove uevent suppression for
subchannels.

Pull driver core updates from Greg KH:
"Here is the big set of driver core patches for 5.15-rc1.

These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did
the following

- changed the bus remove callback to return void

- sysfs iomem_get_mapping rework

Other than those two things, there's only a few small things in here:

- kernfs performance improvements for huge numbers of sysfs users at
once

- tiny api cleanups

- other minor changes

All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue"

s390/cio: Make struct css_driver::remove return void

The driver core ignores the return value of css_remove()
(because there is only little it can do when a device disappears) and
all callbacks return 0 anyhow.

So make it impossible for future drivers to return an unused error code
by changing the remove prototype to return void.

The real motivation for this change is the quest to make struct
bus_type::remove return void, too.
