[PATCH v1] libcamera: media_object: Fix unnecessary copy

[Barnabás Pőcze]

`MediaEntity::ancillaryEntities()` can just return a const lvalue
reference to the underlying array, a copy need not be made. That
was likely the original intention.

Fixes: 9490c664b57a6c ("libcamera: Add members to MediaEntity to support ancillary entities")
