nfp: fix issue of skb segments exceeds descriptor limitation
TCP packets will be dropped if the segments number in the tx skb
exceeds limitation when sending iperf3 traffic with --zerocopy option.
we make the following changes:
Get nr_frags in nfp_nfdk_tx_maybe_close_block instead of passing from
outside because it will be changed after skb_linearize operation.
Fill maximum dma_len in first tx descriptor to make sure the whole
head is included in the first descriptor.
Fixes: c10d12e3dce8 ("nfp: add support for NFDK data path")
