When client has multiple threads that issue io requests
all the time, and the server has a very good performance,
it may cause cpu is running in the irq context for a long
time because it can check virtqueue has buf in the *while*
loop.
So we should keep chan->lock in the whole loop.

tcs_group. The size of tcs (of type - tcs_group) array in rsc_drv is
TCS_TYPE_NR. So the loop index needs to be iterated up to TCS_TYPE_NR only.
