staging: lustre: ptlrpc: avoid warning on missing return
The newly added function triggers a harmless warning: drivers/staging/lustre/lustre/ptlrpc/pack_generic.c: In function 'lustre_shrink_msg': drivers/staging/lustre/lustre/ptlrpc/pack_generic.c:472:1: error: control reaches end of non-void function [-Werror=return-type] This probably happens because LASSERTF() contains an 'unlikely()' that sometimes prevents gcc from analysing the control flow correctly. Adding a return statement here seems harmless and lets us keep that unlikely().
