IB/core: Fix and clean up ib_ud_header_init()
ib_ud_header_init() first clears header and then fills up the various
fields. Later on, it tests header->immediate_present, which it has
already cleared, so the condition is always false. Fix this by adding
an immediate_present parameter and setting header->immediate_present
as is done with grh_present. Also remove unused calculation of
header_len.
