[PATCH] net/sfc: account for data offset on Tx

[Viacheslav Galaktionov <viacheslav.galaktionov@arknetworks.am>]

Memory buffers passed by the application may contain private data,
which must not be sent to the NIC. Omit this private data by using
the actual data address instead of the default one.

Fixes: 3037e6cf3dde ("net/sfc: support regioned NIC DMA memory mapping type")
