I've committed a fix to autofs to use genfs_pathconf().

Unlike FreeBSD, we fall back to return EOPNOSUPP if a filesystem
hasn't implemented a method. FreeBSD has individual defaults for
each method (mostly the 'generic' implementations) and the
default for vop_pathconf is to return EINVAL unconditionally.

N.B. mfs calls genfs_badop, i.e. triggers a panic. This should probably
be changed.
