vcl: favor wr to vls_mt_spool_rwlock

Type: improvement

In a multi-thread single worker app, there can be contention between
many readers and the writers. The writers, which can be close operations
that potentially influence the app logic, could be starved if the
numbers of readers is significant.

To avoid this, always favor writers. Might require fine tuning in the
future.
