Transceiver: Get rid of SoftVector in struct trx_ul_burst_ind

Make the interface using trx_ul_burst_ind more implementation agnostic
as well as easier to use. For instance, we don't care about SoftVector
size one returned from pullRadioVector(); we want to use nbits instead.
As a result, we no longer spend time normalizing guard periods. While at
it, change vectorSLicer to return void since it always returns true.
