vlib: allocating buffers on thread-x and freeing them on thread-y causes
a crash on debug image (VPP-1151)
In debug image, there is extra code to validate the buffer when it is
freed. It uses the hash table to lookup the buffer index with spinlock
to prevent contention. However, there is one spinlock for each worker
thread. So allocating the buffer on thread-x and freeing the same buffer
on thread-y causes the validation to fail on thread-y. The fix is to
have only one spinlock, stored in vlib_global_main.
