qcacld-3.0: Fix WDI 3.0 ethernet header offset

Browse source 
Upon client connection to SAP, WLAN IPA will pass a message
containing client MAC address and ethernet header offset to
IPA driver. Per WDI 3.0, there's no frag_header and
ipa_header prepended in front of ethernet header. Thus
ethernet header length is passed to IPA driver as header
length during interface registration. But in per-client
message, offset passed to IPA driver still accounts for
length of frag_header and ipa_header. As a result packet
queued to event ring will have wrong ethernet header.
And this causes IPA to WLAN TX HW path not work as expected.

Fix is to define frag_header and ipa_header as 0 sized
structure for WDI 3.0 so that ethernet header offset will
be 0.
