The current L2 ARC device code consistently uses psize to increment vs_alloc but varies between psize and lsize when decrementing it. The result of this behavior is that vs_alloc can be decremented more that it is incremented and underflow. This patch changes the code so asize is used anywhere. In addition, it ensures that vs_alloc gets incremented by the L2 ARC device code as buffers are written and not at the end of the l2arc_write_buffers() routine. The latter (and old) way would temporarily underflow vs_alloc as buffers that were just written, would be destroyed while l2arc_write_buffers() was still looping.
