Alexander Motin 44e6a07bff ZIO: Set minimum number of free issue threads to 32
Free issue threads might block waiting for synchronous DDT, BRT or
GANG header reads. So unlike other taskqs using ZTI_SCALE to scale
with number of CPUs, here we also need some amount of threads to
potentially saturate pool reads.  I am not sure we always want the
96 threads we had before ZTI_SCALE introduction at #11966 on small
systems, but lets make it at least 32.

While here, make free taskqs configurable, similar to read and
write ones.
