LU-6160 osd-zfs: Fix refcount_add call

Correct the refcount_add in osd-zfs module's osd_fix_new_dnode
function. The variable 'tag' was undefined and caused osd-zfs
to fail builds against zfs packages with debug enabled.

This small change should enable lustre to be built against
zfs packages that have debug enabled.
