media: ov08x40: Add missing ov08x40_identify_module() call on stream-start

[ Upstream commit ebf185efadb71bd5344877be683895b6b18d7edf ]

The driver might skip the ov08x40_identify_module() on probe() based on
the acpi_dev_state_d0() check done in probe().

If the ov08x40_identify_module() call is skipped on probe() it should
be done on the first stream start. Add the missing call.

Note ov08x40_identify_module() will only do something on its first call,
subsequent calls are no-ops.
