        src/sys/uvm: uvm_anon.c uvm_aobj.c uvm_km.c uvm_pager.c uvm_pdaemon.c
            uvm_swap.c

Log Message:
When retiring a swap device with marked bad blocks on it we should update
the `# swap page in use' and `# swap page only' counters.  However, at the
time of swap device removal we can no longer figure out how many of the
bad swap pages are actually also `swap only' pages.

So, on swap I/O errors arrange things to not include the bad swap pages in
the `swpgonly' counter as follows: uvm_swap_markbad() decrements `swpgonly'
by the number of bad pages, and the various VM object deallocation routines
do not decrement `swpgonly' for swap slots marked as SWSLOT_BAD.
