2022-12-06	media: videobuf2: revert "get_userptr: buffers are always writable"	Hans Verkuil
	Commit 707947247e95 ("media: videobuf2-vmalloc: get_userptr: buffers are always writable") caused problems in a corner case (passing read-only shmem memory as a userptr). So revert this patch. The original problem for which that commit was originally made is something that I could not reproduce after reverting it. So just go back to the way it was for many years, and if problems arise in the future, then another approach should be taken to resolve it. This patch is based on a patch from Hirokazu.

	It's the only user. This also garbage collects the CONFIG_FRAME_VECTOR symbol from all over the tree (well just one place, somehow omap media driver still had this in its Kconfig, despite not using it).
