connmgr: Fix internal packet-in reason code mask.
Starting from OpenFlow 1.4+, OFPR_ACTION is split into four more descriptive
reasons, OFPR_APPLY_ACTION, OFPR_ACTION_SET, OFPR_GROUP, and OFPR_PACKET_OUT.
OVS maintains the new reason code internally, and it currently supports the
first three reason code. If the version of an established OpenFlow connection
is less than 1.4, OVS converts the internal reason code back to OFPR_ACTION to
be backward compatible. However, the internal packet-in reason code mask is
not properly maintained for the older OpenFlow version that may emit the
packet-in messages wth the new reason code. It is because OVS does not enable
the new reason code internally in the reason code mask for older OpenFlow
version. This commit tries to address the aforementioned issue.
