Mark Johnston a2f768f61f FreeBSD: Fix a potential null dereference in zfs_freebsd_fsync() 
In general it's possible for a vnode to not have an associated VM
object.  This happens in particular with named pipes, which have
some distinct VOPs, defined in zfs_fifoops.  Thus, this chunk of
zfs_freebsd_fsync() needs to check for the FIFO case, like other
vm_object_mightbedirty() callers do.

(Note that vn_flush_cached_data() calls are predicated on
zn_has_cached_data() returning true, and it checks for a NULL v_object
pointer already.)
