daedalus-v4l2-dkms: 79256dc -> 6ffe92b — fix kernel panic from #7

Kernel-only bump.  Fixes the hard-reboot regression introduced by
the daedalus-v4l2#7 split-completion design and observed on higgs
(Pi CM5) during the first mpv vaapi-copy playback of 720p H.264:
device_run now removes src + dst from m2m_ctx's rdy_queue at the
moment it picks them up, not at buf_done time.  Without this, a
parked dst_buf (waiting for libavcodec's display-order release)
stayed in the rdy_queue and got re-picked by the next device_run
after SRC_CONSUMED's job_finish released the scheduler — two
inflight entries on the same vb2_buffer, later HAS_PIXELS calls
list_del on an already-detached list_head, panic.

DAEDALUS_PROTO_VERSION stays at 1 — daemon (userspace
daedalus-v4l2) need NOT bump in lockstep with this DKMS update.
The existing daedalus-v4l2 0.1.0+r28+g79256dc is wire-compatible
with daedalus-v4l2-dkms 0.1.0+r30+g6ffe92b.
