John Baldwin e1d15b892a Only handle _PC_MAX_CANON, _PC_MAX_INPUT, and _PC_VDISABLE for TTY devices.
Move handling of these three pathconf() variables out of vop_stdpathconf()
and into devfs_pathconf() as TTY devices can only be devfs files.  In
addition, only return settings for these three variables for devfs devices
whose device switch has the D_TTY flag set.
