6.6-stable review patch. If anyone has any objections, please let me know.

From: Ming Qian ming.qian@oss.nxp.com
commit 46e9c092f850bd7b4d06de92d3d21877f49a3fcb upstream.
Move function mxc_jpeg_free_slot_data() above mxc_jpeg_alloc_slot_data() allowing to call that function during allocation failures. No functional changes are made.
