Fix a pair of conditions in which a concurrent umount can cause NULl pointer dereferences: zfs_sb_teardown - prevent a NULL dereference by not calling dmu_objset_pool with a null z_os. zfs_resume_fs - don't try to unmount with a null z_os. This change makes the ZoL code more consistent with both Illumos and FreeBSD.
