[PATCH] livepatch/klp-build: Fix wrong index in error cleanup loop

[Shihao Ren]

In the funcs allocation failure path, the cleanup loop iterates with
'j' but frees objs[i].funcs, which uses the outer loop index 'i'
instead of the loop variable 'j'. As a result the just-failed (NULL)
entry is freed repeatedly, while the funcs buffers already allocated
for objs[0..i-1] are leaked.

Use objs[j].funcs so the previously allocated entries are correctly
released.
