patch looks good, but can you please fill in the commit message with a
little bit more details and background.

This was found by code inspection by the way, and not tested.
how about:
------------------------------>8-------------8<---------------------------------
When all packets are removed 'i' reaches pkts_to_be_removed + 1, so the
error message was printed upon success, and not when the last packet
wasn't removed.

Isn't there something wrong with this? The patched code looks like it
will output apparently nonsensical messages like "Removed only 10 out of
10 pkts".

yeah, that would make no real sense. I actually just thought about why
we have that error message at all. We might should remove the message
all together.

------------------------------>8-------------8<---------------------------------
When all packets are removed 'i' reaches pkts_to_be_removed + 1, so the error
message was printed upon success, and not when the last packet wasn't removed.
Since it results in nonsensical messages, it was decided to remove the test
altogether.
