[Ruoyu]

This patch gets rid of the below messages while performing a code
analysis with cppcheck.

[sheep/ops.c:884] -> [sheep/ops.c:888]: (performance) Variable 'ret' is
reassigned a value before the old one has been used.
[sheep/ops.c:1149] -> [sheep/ops.c:1166]: (performance) Variable
'locked' is reassigned a value before the old one has been used.
