[PATCH 2/4] media: mediatek: vcodec: Drop unnecessary variable

[Fei Shao <fshao@xxxxxxxxxxxx>]

It's unclear why only mem->size has local copies without particular
usage in mtk_vcodec_mem_alloc() and mtk_vcodec_mem_free(), and they
seem removable.

Drop them to make the code visually consistent, and update printk format
identifier accordingly.
