Improve zvol symlink handling.
Change the zvol helper program to replace any embedded spaces
in the pool or dataset names with '+' to ensure we have valid
symlinks.
The '+' character was choosen because it is not a valid character
for a dataset name but it is allowed by udev. This ensures that
all dataset names with an embedded space will be translated to
a unique /dev/zvol/ symlink.
