Subject: [PATCH] mbuf: explicit casts of reference counter

[ upstream commit f6ffdf1c2c1cfbb2a3cbce246b545560609abeb5 ]

differences to the atomic16 are signed, but the
atomic16 itself is unsigned.  It needs to be
made explicit with casts.

Fixes: af75078fece3 ("first public release")
Fixes: a53aa2b9f3be ("mbuf: support attaching external buffer")
