[ Upstream commit b4e26c6fc1b3c225caf80d4a95c6f9fcbe959e17 ]

When STREAMON(CAP) is called after STREAMON(OUT), the driver was failing to
switch states from VPU_INST_STATE_OPEN to VPU_INST_STATE_INIT_SEQ and
VPU_INST_STATE_PIC_RUN because the capture queue streaming boolean had not
yet been set to true. This led to a hang in the encoder since the state
was stuck in VPU_INST_STATE_OPEN. During the second call to
start_streaming, the sequence initialization and frame buffer allocation
should occur.
