mptcp: pm: in-kernel: remove stale_loss_cnt

It is currently not used.

It was in fact never used since its introduction in commit ff5a0b421cb2
("mptcp: faster active backup recovery"). It was probably initially
added to struct pm_nl_pernet during the development of this commit,
before being added to struct mptcp_pernet in ctrl.c, but not removed
from the first place.
