kernel - Fix swap space leak
* swp_pager_meta_free_callback() had a bug where the last swap block
in the swblock{} structure was not being freed from the swap bitmap.
* Also fix two rare race conditions. swp_pager_freeswapspace() can
block, causing the VM object token to be temporarily unlocked. Deal
with the race by not decrementing the swb_count field until after
swp_pager_freeswapspace() is called.
