There's no need to re-read EFR after we've recently written it; the
register is a configuration register which doesn't change its value
without us writing to it.

Removing this re-reading avoids the possibility that we end up with
up->efr having the ECB bit set, which should only be temporarily set
when accessing the enhanced features.
