mischivus b40cd91913 Fix s_active leak in zfsvfs_hold() when z_unmounted is true

When getzfsvfs() succeeds (incrementing s_active via
zfs_vfs_ref()), but z_unmounted is subsequently found to
be B_TRUE, zfsvfs_hold() returns EBUSY without calling
zfs_vfs_rele(). This permanently leaks the VFS superblock
s_active reference, preventing generic_shutdown_super()
from ever firing, which blocks dmu_objset_disown() and
makes the pool permanently unexportable (EBUSY).

Add the missing zfs_vfs_rele() call, guarded by
zfs_vfs_held() to handle the zfsvfs_create() fallback
path where no VFS reference exists. This matches the
existing cleanup pattern in zfsvfs_rele().
