bpf: let verifier to calculate and record max_pkt_offset
In check_packet_access, update max_pkt_offset after the offset has passed
__check_packet_access.
It should be safe to use u32 for max_pkt_offset as explained in code
comment.
Also, when there is tail call, the max_pkt_offset of the called program is
unknown, so conservatively set max_pkt_offset to MAX_PACKET_OFF for such
case.
