bus: mhi: ep: Fix off by one in mhi_ep_process_cmd_ring()
The > comparison should be changed to >= to prevent an out of bounds
access into the mhi_cntrl->mhi_chan[] array. The mhi_cntrl->mhi_chan[]
array is allocated in mhi_ep_chan_init() and has mhi_cntrl->max_chan
elements.
Fixes: 6de4941c0215 ("bus: mhi: ep: Check if the channel is supported by the controller")
