[PATCH 3/3] media: atomisp: handle errors at sh_css_create_isp_params()

[Mauro Carvalho Chehab]

The succ var tracks memory allocation erros on this function.

Fix it, in order to stop this W=1 Werror in clang:

drivers/staging/media/atomisp/pci/sh_css_params.c:2430:7: error: variable 'succ' set but not used [-Werror,-Wunused-but-set-variable]
        bool succ = true;
             ^
