isofs: pass the name buffer size to get_rock_ridge_filename()

get_rock_ridge_filename() assembles a name from one or more NM entries
into a buffer allocated by its caller.  It is not told how big that
buffer is, and instead stops adding NM entries once the name would
exceed NAME_MAX, relying on the callers' buffer being larger.

Pass the size in and check against it.  Both callers pass NAME_MAX + 1,
so the behaviour is unchanged: an NM entry that would take the name
past 255 bytes is dropped, together with any that follow, and the
entries before it are returned.
