[PATCH v13 07/12] media: mediatek: jpeg: fix resolution change event handling in decoder

[Kyrie Wu <kyrie.wu@mediatek.com>]

This patch refines the handling of resolution change events within
JPEG decoder worker. The `mtk_jpeg_set_queue_data` function is now
called to set up queue data before signaling a source change through
`mtk_jpeg_queue_src_chg_event`. By reorganizing these calls, the
patch ensures that necessary queue information is updated prior to
transitioning the context state to `MTK_JPEG_SOURCE_CHANGE`.
A condition is added to exit early if the context is already in the
`MTK_JPEG_SOURCE_CHANGE` state, preventing redundant operations and
improving processing efficiency.
