FreeBSD: Satisfy ASSERT_VOP_IN_SEQC()

Browse Source 
zfs_aclset_common() might be called for newly created or not even
created vnodes, that triggers assertions on newer FreeBSD versions
with DEBUG_VFS_LOCKS included into INVARIANTS.  In the first case
make sure to call vn_seqc_write_begin()/_end(), in the second just
skip the assertion.

The similar has to be done for project management IOCTL and file-
bases extended attributes, since those are not going through VFS.
