gpu: ipu-v3: ipu-csi: bool test doesn't need a comparison to false

Bool initializations should use true and false. Bool tests don't need
comparisons. Based on contributions from Joe Perches, Rusty Russell
and Bruce W Allan.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/boolinit.cocci.
