libbpf: Remove unneeded check for flags during tc detach

Browse Source 
Coverity complained about this being unreachable code. It is right
because we already enforce flags to be unset, so a check validating
the flag value is redundant.

Fixes: 715c5ce454 ("libbpf: Add low level TC-BPF management API")
