    fix handover: handle_ph_ra_ind(): evaluate ra_ind before msgb_trim()
    
    Commit c2b4c668f3510b7b0baace749c5a310959010e90
    I3b989580cb38082e3fd8fc50a11fedda13991092 introduces evaluation of ra_ind
    members below the msgb_trim() call that actually invalidates ra_ind.
    A symptom is that it breaks detection of Handover RACH, wich always ends up
    with lchan == NULL and interpreting all RACH as chan_nr == 0x88.
    
    Fix: do all evaluation of ra_ind before the msgb_trim(), for osmo-bts-sysmo,
    litecell-15 and octphy.
    
    To guard against similar mistakes in the future, set ra_ind = NULL before the
    msgb_trim() call.
