plugins/vcgn-plugin: Fix vpp hang with pthread spinlock
Currently, pthread spinlock is initialized in macro ASSERT, thus the spinlock only will be initialized when CLIB_ASSERT_ENABLE is true. But CLIB_ASSERT_ENABLE depends on CLIB_DEBUG been set. Mostly, CLIB_DEBUG is zero, so spinlock will never been initialized, which will lead vpp hang when try to hold the lock. This patch fix this issue.
