octeontx2-af: Fix start and end bit for scan config 



In the current driver, NPC exact match feature was not getting
enabled as configured bit was not read properly.
for_each_set_bit_from() need end bit as one bit post
position in the bit map to read NPC exact nibble enable
bits properly. This patch fixes the same.
