Issue:
When aggrigated uprobe is executed, it never correctly returns
from trampoline_uprobe_handler's retprobe_instance list iteration
if it was called inside anther profiled function.
Solution:
It happened, because break condition was never satisfied: first
time because orig_ret_addr == tramp_addr, all other times because
p, which is pointer to the first uprobe, is not equal to up, which
is other probes related uprobe.
So, this fix removes p and up comparsion as a mistake.
