The earlier commits [0] removed duplicated code from bpf_setsockopt().
This series is to remove duplicated code from bpf_getsockopt().
Unlike the setsockopt() which had already changed to take
the sockptr_t argument, the same has not been done to
getsockopt(). This is the extra step being done in this
series.

v2:
- The previous v2 did not reach the list. It is a resend.
- Add comments on bpf_getsockopt() should not free
the saved_syn (Stanislav)
- Explicitly null-terminate the tcp-cc name (Stanislav)
Looks great!
