[PATCH v5 13/20] media: rkvdec: h264: Fix reference frame_num wrap for second field

[Nicolas Dufresne]

From: Jonas Karlman <jonas at kwiboo.se>

When decoding the second field in a complementary field pair the second
field is sharing the same frame_num with the first field.

Currently the frame_num for the first field is wrapped when it matches the
field being decoded, this caused issues decoding the second field in a
complementary field pair.

Fix this by using inclusive comparison: 'less than or equal'.
