picture.c: remove the 0xab sentinel write into CAPTURE buffer first
32 bytes pre-QBUF + the OUTPUT hex-dump pre-QBUF. Both were iter1
diagnostics for "where does the buffer write go?" investigation.
surface.c: remove the post-DQBUF CAPTURE Y-plane hex-dump + luma
variance signal. The msync(MS_SYNC|MS_INVALIDATE) was added as a
companion fix for the cached-mmap issue surfaced by the dump itself —
removing the dump removes the need for the msync.
With iter1+iter2+iter3+iter4 fixes landed, these dumps fire on every
single frame and produce hundreds of MB of log noise during sustained
decode. Now gone.
