[libvirt] [PATCH] openvzRegister: Check for error return

[John Ferlan]

A recent change to openvz_driver.c caused Coverity to make additional
comparisons and find that the openvzRegister() was not checking the
status of virRegisterDriver() call like other callers and thus generated
a CHECKED_RETURN condition
