Subject: [PATCH] media: atomisp: avoid memory leak in ia_css_pipe_create_cas_scaler_desc_single_output()

ia_css_pipe_create_cas_scaler_desc_single_output() may fail,
so add cleanup by ia_css_pipe_destroy_cas_scaler_desc()
rather than simply exiting the function.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: a49d25364dfb ("staging/atomisp: Add support for the Intel IPU v2")
