[ Upstream commit bfd862a7e9318dd906844807a713d27cdd1a72b1 ]
'$cin' and '$sin' variables are local to a function: they are then not
available from the cleanup trap.
Instead, we need to use '$large' and '$small' that are not local and
defined just before setting the trap.
Without this patch, running this script in a loop might cause a:
write: No space left on device
issue.
Fixes: 1a418cb8e888 ("mptcp: simult flow self-tests")
