media: atomisp: Add check for rgby_data memory allocation failure
[ Upstream commit ed61c59139509f76d3592683c90dc3fdc6e23cd6 ]
In ia_css_3a_statistics_allocate(), there is no check on the allocation
result of the rgby_data memory. If rgby_data is not successfully
allocated, it may trigger the assert(host_stats->rgby_data) assertion in
ia_css_s3a_hmem_decode(). Adding a check to fix this potential issue.
Fixes: a49d25364dfb ("staging/atomisp: Add support for the Intel IPU v2")
