media: bcm2835-unicam: Do not stop streaming in unicam_release

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

unicam_release calls _vb2_fop_release, which will call stop_streaming
if that particular node was streaming. Calling it unconditionally (as
the code was) means that if a second handle was opened eg to alter
a setting, on closing that connection it also stopped Unicam.
