Correct two errors in PG_BUSY management by vm_page_cowfault().  Both
errors are in rarely executed paths.
1. Each time the retry_alloc path is taken, the PG_BUSY must be set again.
   Otherwise vm_page_remove() panics.
2. There is no need to set PG_BUSY on the newly allocated page before
   freeing it.  The page already has PG_BUSY set by vm_page_alloc().
   Setting it again could cause an assertion failure.
