Modified Files:
        src/sys/dev/filemon: filemon.c filemon.h filemon_wrapper.c

Log Message:
Be a bit more paranoid about hijacking (and restoring) syscall function
pointers.  Ensure that we have the correct "old" values before setting
new values, for both "intall" and "deinstall".

XXX This is NOT intended to encourage additional cases of hijacking!  If
XXX some other hijack feature ever gets committed, this code should be
XXX moved to (most likely) kern/kern_syscall.c.
