mptcp: pm: kernel: reset fullmesh counter after flush
This variable counts how many MPTCP endpoints have a 'fullmesh' flag
set. After having flushed all MPTCP endpoints, it is then needed to
reset this counter.
Without this reset, this counter exposed to the userspace is wrong, but
also non-fullmesh endpoints added after the flush will not be taken into
account to create subflows in reaction to ADD_ADDRs.
Fixes: f88191c7f361 ("mptcp: pm: in-kernel: record fullmesh endp nb")
