TIPC fix 7387a72c5f8 needed for v5.10.x and v5.13.x

A bad "Fixes" SHA in mainline 7387a72c5f8 references a non-public SHA, instead of referencing f8dd60de1948 -- see:

https://lore.kernel.org/lkml/20210817075644.0b5123d2@canb.auug.org.au/

This matters to -stable since the broken commit is here:

stable-queue$git grep -l f8dd60de1948 releases/5.10.56/tipc-fix-implicit-connect-for-syn.patch releases/5.13.8/tipc-fix-implicit-connect-for-syn.patch

and hence those releases will need mainline 7387a72c5f8 applied but I suspect automatic Fixes: parsing won't "see" it.

Thanks, Paul.
