media: v4l2-fh: define v4l2_fh struct regardless of condition
v4l2_fh struct define differently by CONFIG_V4L2_MEM2MEM_DEV.
If some vendors use CONFIG_V4L2_MEM2MEM_DEV by module,
it can make the mismatch of v4l2_fh sturct.
By the mismatch, the following error occurs.
===============================
[ 7.533506] v4l2_mem2mem: disagrees about version of symbol video_devdata
[ 7.533594] v4l2_mem2mem: Unknown symbol video_devdata (err -22)
[ 7.535319] v4l2_mem2mem: disagrees about version of symbol v4l2_event_pending
[ 7.542532] v4l2_mem2mem: Unknown symbol v4l2_event_pending (err -22)
===============================
So v4l2_fh struct is modified to does not have dependency
for CONFIG_V4L2_MEM2MEM_DEV.
