Linux: Fix use-after-free in zfsvfs_create()
Coverity reported that we pass a pointer to zfsvfs to
`dmu_objset_disown()` after freeing zfsvfs in zfsvfs_create_impl() after
a failure in zfsvfs_init().

We have nearly identical duplicate versions of this code for FreeBSD and
Linux, but interestingly, the FreeBSD version of this code differs in
such a way that it does not suffer from this bug. We remove the
difference from the FreeBSD version to fix this bug.
