[CARBONDATA-3181][BloomDataMap] Fix access field error for BitSet in bloom
filter
**Problem**
java.lang.IllegalAccessError is thrown when query on bloom filter without
compress on CarbonThriftServer. Detailed log ss pasted at bottom.
**Analyse**
similar problem was occur when get/set BitSet in CarbonBloomFilter, it uses
reflection to solve. We can do it like this. Since we have set the BitSet
already, another easier way is to call super class method to avoid accessing it
from CarbonBloomFilter
**Solution**
if bloom filter is not compressed, call super method to test membership
