u2fd: Set vendor mode before every U2F command

This is to work around the fact that cr50 loses
U2F state during deep sleep, and u2fd doesn't know
when that has happened.

BUG=b:140361043, chromium:998008
TEST=build u2fd and flash to eve
     register on webauthn.io
     lock screen, wait for suspend, cr50 to enter deep sleep
     authenticate on webauthn.io
