[PATCH v5 3/3] staging: dgnc: remove redundant !ch checks

[Giedrius StatkeviÄius]

Remove checks that are redundant since we don't have boards with partially
initialized ->channels[i].

Signed-off-by: Giedrius StatkeviÄius <giedrius.statkevicius@xxxxxxxxx>

v5: there was a mistake in v4 in which a wrong check was deleted in cls_tasklet
v4: splitted this from the one patch.
