DeHackEd 76a1232ee7 Use boot_ncpus in place of max_ncpus in taskq_create 
Due to hotplug support or BIOS bugs sometimes max_ncpus can be
an absurdly high value. I have a system with 32 cores/threads
but reports max_ncpus == 440. This many threads potentially
cripples the system during arc_prune floods for example.

boot_ncpus is the number of working CPUs when called so use
that instead.
