qcacld-3.0: Add frag_header to support pre-wdi2.0 platform

Browse Source 
wdi2.0 feature adds extra 2 bytes to frag_header and thus hdr_len
to IPA HW also adds 2 bytes. This change breaks pre-wdi2.0 platform
with WiFi FW discarding all TX traffic since packet payload is
with an extra 2-byte offset.

Fix is to add frag_header structure with pre-wdi2.0 pattern.
