Move DTIM period configuration into Beacon set operation

This is needed to make mac80211 work with multi-BSS configuration. The
previous design ended up setting DTIM period for secondary BSSes before
setting the Beacon and driver_nl80211.c was not really prepared for
that. Eventually, the Beacon configuration routines should be combined
into a single driver operation, but for now, just moving this call is
the simplest workaround.
