[PATCH v4 4/7] media: vsp1: wpf: Propagate vsp1_rwpf_init_ctrls()

[Jacopo Mondi <jacopo.mondi+renesas@xxxxxxxxxxxxxxxx>]

vsp1_wpf.c calls vsp1_rwpf_init_ctrls() to initialize controls that
are common between RPF and WPF.

However, the vsp1_wpf.c implementation does not check for the function
call return value. Fix this by propagating to the caller the return
value.

While at it, drop a duplicated error message in wpf_init_controls() as
the caller already report it.
