Modified Files:
        src/sys/kern: kern_synch.c subr_pserialize.c

Log Message:
Change the place to check if a context switch doesn't happen within a pserialize read section

The previous place (pserialize_switchpoint) was not a good place because at that
point a suspect thread is already switched so that a backtrace gotten on
a KASSERT failure doesn't point out where a context switch happens.
