added an error_t to netfs_startup

[James A Morrison]

Hi,

  This patch is cosmetic, but it helped me debug since I couldn't get
gdb to print errno, where it would print error.

  Is this the better way to return the error?  If yes, I will go through
the rest of the hurd source looking for similar situations and fix them
as well.
