ethdev: update flow item GTP QFI definition

'qfi' field is 8 bits which represent single bit for
PPP (paging Policy Presence) single bit for RQI
(Reflective QoS Indicator) and 6 bits for QFI
(QoS Flow Identifier)
This is based on RFC 38415-g30
https://www.3gpp.org/ftp/Specs/archive/38_series/38.415/38415-g30.zip

Updated the doxygen comment and the mask for 'qfi'
to properly identify the full 8 bits of the field.

note: changing the default mask would cause different
patterns generated by testpmd.
