media: ipu-bridge: Fix null pointer deref on SSDB/PLD parsing warnings

[ Upstream commit 284be5693163343e1cf17c03917eecd1d6681bcf ]

When ipu_bridge_parse_rotation() and ipu_bridge_parse_orientation() run
sensor->adev is not set yet.

So if either of the dev_warn() calls about unknown values are hit this
will lead to a NULL pointer deref.

Set sensor->adev earlier, with a borrowed ref to avoid making unrolling
on errors harder, to fix this.
