avcodec/cuviddec: correctly set key_frame with interlaced content
Fixes #9283
This fixes setting of 'key_frame' flag in AVFrame when input h264 packets represents individual fields of interlaced video.
In this case, pairs of two consecutive fields represents a single decoded picture and have identical 'CurrPicIdx', however, only
the first field is entirely intra-coded and has the flag 'intra_pic_flag' set and the second field was resetting the flag before
it was even read in the function 'cuvid_output_frame'.
