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. PR: 142102 (second part) MFC after: 1 week
