media: videobuf2-core: check for q->error in vb2_core_qbuf()
The vb2_core_qbuf() function didn't check if q->error was set. It is
checked in __buf_prepare(), but that function isn't called if the buffer
was already prepared before with VIDIOC_PREPARE_BUF.
So check it at the start of vb2_core_qbuf() as well.
