[PATCH net 08/15] selftests: mptcp: join: no extra msg if no counter

[Matthieu Baerts (NGI0)]

The checksum and fail counters might not be available. Then no need to
display an extra message with missing info.

While at it, fix the indentation around, which is wrong since the same
commit.

Fixes: 47867f0a7e83 ("selftests: mptcp: join: skip check if MIB counter not 
supported")
