Fix warnings in ContikiMAC

Browse Source 
../..//core/net/mac/contikimac/contikimac.c:503:11: warning: variable
‘seqno’ set but not used [-Wunused-but-set-variable]
../..//core/net/mac/contikimac/contikimac.c:496:7: warning: variable
‘len’ set but not used [-Wunused-but-set-variable]

Both of these variables are only used if RDC_CONF_HARDWARE_ACK is not
true.
Their definitions and use have been moved into #ifdef guards so they do
not appear if RDC_CONF_HARDWARE_ACK is set.
