Brian Behlendorf dc1b30224f Never spin in kmem_cache_alloc() ...

If we are reaping from the cache and a concurrent allocation
occurs then the caller must block until the reaping is complete.
This is signaled by the clearing of the KMC_BIT_REAPING bit.

Otherwise the caller will be in a tight loop which takes and
releases the skc->skc_cache lock.  When there are multiple
concurrent callers the system will thrash on the lock and
appear to lock up.
