media: sun6i-csi: Allow the video device to be open multiple times
[ Upstream commit
8ed852834683ebe064157e069af8dfb41cad6403 ]
Previously it was possible, but a recent fix for uninitialized
`ret` variable broke this behavior.
v4l2_fh_is_singular_file() check is there just to determine
whether the power needs to be enabled, and it's not a failure
if it returns false.
