pn_offset field was only set if header protection cannot be removed. Extend the usage of this field : it is now set everytime on packet parsing in qc_lstnr_pkt_rcv(). This change helps to clean up API of Rx functions by removing unnecessary variables and function argument. This change has no functional impact. It is a part of a refactoring series on qc_lstnr_pkt_rcv(). The objective is facilitate integration of FD-owned socket patches. This should be backported up to 2.6.
