'zfs share -a' should clean noauto exports
This is a follow on to PR #10688 where `zfs share -a` allows the 
sharing of canmount=noauto datasets if they are mounted.  However, 
when a dataset with canmount=noauto is not mounted, the command 
should also purge any existing entries from the exports file. 
Otherwise, after a reboot, the nfs server attempts to export the 
underlying mountpath, not the dataset. This can lead to a hard hang 
for existing client mounts.

Instead of just skipping the adding of an export if not mounted 
and canmount=noauto, have it also remove an existing export of the 
dataset so that, after a reboot, we don't export an unmounted dataset.
