openvz: Handle getline failures in openvzReadConfigParam properly

Browse Source 
The regression fix in 3aab7f2d6b068f0 altered the error handling.
getline returns -1 on failure to read a line (including EOF). The
original openvzReadConfigParam function using openvz_readline only
treated EOF as not-found. The current getline version treats all
getline failures as not-found.

This patch fixes this and distinguishes EOF from other getline
failures.
