Some style(9) fixes in order to fabricate a commit to denote that
the commit message for r201896 actually should have read:

As nfsm_srvmtofh_xx() assumes the 4-byte alignment required by XDR
ensure the mbuf data is aligned accordingly by calling nfs_realign()
in fha_extract_info(). This fix is orthogonal to the problem solved
by r199274/r199284.
