Possible Typo in Victoria Metrics fallback version

[sugadge]

Hi Team,
Looks like below is typo -

carbonapi/zipper/protocols/victoriametrics/feature_set.go

Line 185 in d53ae1c

minFeatureSet = versionToFeatureSet(logger, "c.fallbackVersion")

This is causing metrics/find API to use /api/v1/series?match and not able to pick up the optimizations already available in code.
If we remove the quotes around the version ( i.e. passing actual fallback version from the config file ), then it seems to work fine.
