mptcp: fix error mibs accounting
The current accounting for MP_FAIL and FASTCLOSE is not very
accurate: both can be increased even when the related option is
not really sent. Move the accounting into the correct place.
Fixes: eb7f33654dc1 ("mptcp: add the mibs for MP_FAIL")
Fixes: 1e75629cb964 ("mptcp: add the mibs for MP_FASTCLOSE")
