HID: bpf: make part of struct hid_device writable
It is useful to change the name, the phys and/or the uniq of a
struct hid_device during .rdesc_fixup().
For example, hid-uclogic.ko changes the uniq to store the firmware version
to differentiate between 2 devices sharing the same PID. In the same
way, changing the device name is useful when the device export 3 nodes,
all with the same name.
