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

Browse Source 
[ Upstream commit c60a6b90e7890453f09e0d2163d6acadabe3415b ]

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.
