[Devel] [PATCH hci-8.1 7/8] ms/mptcp: being below memory limit is a likely() condition

[Eva Kurchatova <eva.kurchatova@virtuozzo.com>]

From: Paolo Abeni <pabeni@redhat.com>

The current compiler hint annotation is wrong, due to inverted
logic in the previous revision of the relevant code.

Fixes: e468d371180d ("mptcp: implemented OoO queue pruning")
