You will also need these four fixes, then it should work:

cmd: zip: Add missing unmap_sysmem() for buffers in the unzip command
cmd: zip: Use map_sysmem() with buffers in the zip command
cmd: unzip: Use map_sysmem() with buffers in the gzwrite command
gunzip: Fix len parameter in function signature
