The previous commit changed the behavior of nsdispatch() in the case where an /etc/nsswitch.conf file was present, but could not be opened (e.g. due to permissions).  Previously, the open failure condition was suppressed, and the built-in defaults were used.  In revision 1.11, however, propagated the open failure causing all nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs including getpwnam and gethostbyname unconditionally failed.

This commit restores the previous behavior.
