Fizz: Suppress EC_CMD_PD_GET_LOG_ENTR debug log

Host command handler prints every single host command except when
commands are repeated back-to-back. Some commands do not provide
useful info when studying feedback reports or what is worse they
may hide critical info by flooding the EC log.

BUG=chromium:803955
BRANCH=none
TEST=Observe 'HC 0x115' is not printed.
