[ Upstream commit 9aafbfa5f57a4b75bafd3bed0191e8429c5fa618 ]
rtas-error-log-max is not the name of an RTAS function, so rtas_token()
is not the appropriate API for retrieving its value. We already have
rtas_get_error_log_max() which returns a sensible value if the property
is absent for any reason, so use that instead.
Fixes: 8d633291b4fc ("powerpc/eeh: pseries platform EEH error log retrieval")
