Motivation and Context

zfs.sh already can load and unload, so why not both?

This is convenient when developing changes to the module and you want
to rapidly make some changes, rebuild the module, reload the module,
and test the changes.

Description

Add a variable in zfs.sh to control whether to load independently from whether to unload.
Set the variable according to the given flags.

How Has This Been Tested?

$ sudo ./scripts/zfs.sh -vr
