Do not return a partially-initialized BufferPool

Do not return a partially-initialized BufferPool struct, because we
cannot tell if the pool_mutex member of the struct has been initialized
by a pthread_mutex_init() call. Although the pool_mutex member is
zero-initialized by aom_calloc(), it may not be considered as
initialized by the pthread library, so if pthread_mutex_init() is not
called to initialize pool_mutex, the pthread_mutex_destroy() call on
pool_mutex may fail.

An alternative solution is to add a `bool pool_mutex_initialized` member
to the BufferPool struct.
