Don't fail vma tracking mmap callback if module is already known.

An -EEXIST returned by stap_add_vma_map_info() just indicates that the
module is currently in stap's vma cache; it isn't a real issue. Calling
_stp_error() when this occurs causes stap to exit when there isn't a
real bug. Ignore the -EEXIST error to avoid breakage.
