There appears to be a missing break in the TCP_BPF_SNDCWND_CLAMP case.
Currently the non-error path where val is greater than zero falls through
to the default case that sets the error return to -EINVAL. Add in
the missing break.Detected by CoverityScan, CID#1449376 ("Missing break in switch")
Fixes: 13bf96411ad2 ("bpf: Adds support for setting sndcwnd clamp")
