doc: add statistics fixes in release notes

This patch updates the release notes to include the changes
made (by me), which were not appropriately documented at the time.
Hence, this patch fixes a number of missing docs,

Fixes: e81a315e5dc5 ("ixgbe: add MAC short packet discard count to Rx errors")
Fixes: 48dd1a82a615 ("ixgbe: remove mac fault counts from Rx errors")
Fixes: 256ff05a9cae ("ixgbe: fix Rx errors statistics for UDP checksum")

Also, the CRC byte removal was not added to release notes, so
Fixes: 156c5a8cf913 ("e1000: remove CRC size from byte counters")
Fixes: c03fcee9abbd ("ixgbe: remove CRC size from byte counters")
Fixes: 0834d1524dee ("i40e: remove CRC size from byte counters")
