parser_bison: missing relational operation on flag list
Complete e6c32b2fa0b8 ("src: add negation match on singleton bitmask
value") which was missing comma-separated list of flags.
This patch provides a shortcut for:
tcp flags and fin,rst == 0
which allows to check for the packet whose fin and rst bits are unset:
# nft add rule x y tcp flags not fin,rst counter
