avcodec/h264_ps: Remove ALLOW_INTERLACED cruft

Since e1027ab,
ALLOW_INTERLACED is no longer defined in h264_ps.c,
leading to a warning when encountering an SPS compatible
with MBAFF. This warning was always nonsense, because
ff_h264_decode_seq_parameter_set() is also used by the parser
and it makes no sense for the parser to warn about missing
decoder features; after all, it is not a parser's job
to warn when a feature is unsupported by a decoder
(and in this case it is even weirder, because even if the H.264
decoder is disabled, the warning will only be shown for MBAFF
sequence parameter sets). So remove the warning in h264_ps.c.
