staging: media: atomisp: fix map and vmap leaks in stat buffer allocation

There are memory leaks in
drivers/staging/media/atomisp/pci/atomisp_compat_css20.c.

In atomisp_css_allocate_stat_buffers(), s3a_map is allocated by
ia_css_isp_3a_statistics_map_allocate() and its backing memory is
mapped via hmm_vmap(). When dis_buf allocation fails, the error path
frees s3a_data but does not unmap or free s3a_map. Similarly, when
md_buf allocation fails, neither s3a_map nor dvs_map (and their hmm
vmaps) are freed.

Add the missing hmm_vunmap() and map free calls on both error paths,
matching the cleanup order used in atomisp_css_free_3a_buffer() and
atomisp_css_free_dis_buffer().
