Do not delegate a work to geom event thread which can be done inline.

In particular, swapongeom_ev() needed event thread context when swap
pager configuration was performed under Giant and geom asserted that
Giant is not owned.  Now both of the reason went away.

On the other hand, note that swpageom_release() is called from the
bio_done context, and possible close cannot be performed inline.

Also fix some minor issues.  The swapgeom() function does not use the
td argument, remove it.  Recheck that the vnode passed is still VCHR
and not reclaimed after the lock.
