[PATCH v2 1/2] livepatch: Fix wrong index in funcs cleanup error path

[Yafang Shao <laoar.shao@gmail.com>]

In the object allocation loop, when kzalloc() for funcs fails, the
cleanup loop uses `objs[i].funcs` instead of `objs[j].funcs`. Since
`objs[i].funcs` is still NULL at that point, it repeatedly calls
kfree(NULL) and leaks all previously allocated funcs arrays.

Fixes: 59adee07b568 ("livepatch/klp-build: Add stub init code for livepatch modules")
