rtph264pay: avoid double buffer unmap on error

I get a segfault in gstrtph264pay.c when the call to
gst_rtp_h264_pay_set_sps_pps in gst_rtp_h264_pay_setcaps fails. There is a
double gst_buffer_unmap. The buffer has just been unmapped, and then it is
unmapped again when we goto error at the set_sps_pps_failed label.

The attached patch is a suggested fix for this problem.
