Revert two renamings backported from master

The original names were more intuitive: the generate_counter counts the
number of generate requests, and the reseed_counter counts the number
of reseedings (of the principal DRBG).

    reseed_gen_counter  -> generate_counter
    reseed_prop_counter -> reseed_counter

This partially reverts commit 35a34508ef4d649ace4e373e1d019192b7e38c36.
