Subject: [PATCH] compat_ioctl, cdrom: Replace .ioctl with .compat_ioctl in four appropriate places

From: Adam Williamson <awilliam@redhat.com>

Arnd Bergmann inadvertently typoed these in d320a9551e394 and
64cbfa96551a; they seem to be the cause of
https://bugzilla.redhat.com/show_bug.cgi?id=1801353 , invalid
SCSI commands when udev tries to query a DVD drive.

[arnd] Found another instance of the same bug, also introduced
in my compat_ioctl series.

Fixes: d320a9551e39 ("compat_ioctl: scsi: move ioctl handling into drivers")
Fixes: 64cbfa96551a ("compat_ioctl: move cdrom commands into cdrom.c")
Fixes: c103d6ee69f9 ("compat_ioctl: ide: floppy: add handler")
