qemu-img: fix rebase src_cache option documentation
The src_cache option (-T) specifies the cache mode for backing files.
It applies both the image's old backing file as well as the new backing
file:
ret = bdrv_open(&bs_old_backing, backing_name, NULL, NULL, src_flags,
old_backing_drv, &local_err);
if (ret) {
...
}
if (out_baseimg[0]) {
bs_new_backing = bdrv_new("new_backing", &error_abort);
ret = bdrv_open(&bs_new_backing, out_baseimg, NULL, NULL, src_flags,
new_backing_drv, &local_err);
if (ret) {
...
}
}
The documentation only mentions the new backing file but it really
applies to both.
