device_cgroup: Cleanup cgroup eBPF device filter code
Original cgroup v2 eBPF code for filtering device access made it possible to compile with CONFIG_CGROUP_DEVICE=n and still use the eBPF filtering. Change commit 4b7d4d453fc4 ("device_cgroup: Export devcgroup_check_permission") reverted this, making it required to set it to y. Since the device filtering (and all the docs) for cgroup v2 is no longer a "device controller" like it was in v1, someone might compile their kernel with CONFIG_CGROUP_DEVICE=n. Then (for linux 5.5+) the eBPF filter will not be invoked, and all processes will be allowed access to all devices, no matter what the eBPF filter says.
