Omar Sandoval 64de9ef829 libdrgn: log: fix typos in drgn_error_log_{critical,error}()
The log levels are DRGN_LOG_CRITICAL and DRGN_LOG_ERROR, not
DRGN_LOG_CRIT and DRGN_LOG_ERR. These macros aren't being used anywhere
yet, so it wasn't caught before.

Fixes: c1a2792e6a ("libdrgn: add simple logging framework")
