fix regression in zfs volume activation

Browse Source 
commit 815df2dd08 introduced a small issue
when activating linked clone volumes - the volname passed contains
basevol/subvol, which needs to be translated to subvol.

using the path method should be a robust way to get the actual path for
activation.

Found and tested by building the package as root (otherwise the zfs
regressiontests are skipped).
