usb: gadget: f_tcm: Limit number of sessions
Only allocate up to UASP_SS_EP_COMP_NUM_STREAMS number of session tags.
We should not be using more than UASP_SS_EP_COMP_NUM_STREAMS of tags due
to the number of commands limit we imposed. Each command uses a unique
tag. Any more than that is unnecessary. By limiting it, we can detect an
issue in our driver immediately should we run out of session tags.
