jdolecek 94b1798c8c struct ntnode: g/c i_uid, i_gid, i_mode - use directly appropriate
ntnode->ntmp->ntm_* values
ntfs_inactivate(): as NTFS doesn't support any filesystem changes,
	it's not needed to check whether the file handle is stale;
	the check was bogus anyway - besides the value of vp->v_usecount
	was checked with unlocked vnode, the vnode was unnecessarily
	_always_ recycled when the filesystem containing it has been
	mounted with mask (-i parameter to mount_ntfs(1))
	not specified or 0 -- unbelievable, but true
ntfs_reclaim(): don't call VOP_UNLOCK() even on FreeBSD - it's not
	done for any other their filesystem, so it should not be done even
	for NTFS
ntfs_access(): remove the commented-out check for immutable flag, it doesn't
	make sense for NTFS
other miscelaneous cosmetic cleanups
