mptcp: fix address removal logic in mptcp_pm_nl_rm_addr

Browse Source 
Fix inverted WARN_ON_ONCE condition that prevented normal address
removal counter updates. The current code only executes decrement
logic when the counter is already 0 (abnormal state), while
normal removals (counter > 0) are ignored.
