soundwire: qcom: Fix port exhaustion check in stream_alloc_ports
find_first_zero_bit(mask, n) returns n (not n+1) when all bits are set,
so the guard `pn > maxport` is never true on exhaustion. The driver
would silently call set_bit(maxport, port_mask) and assign the
out-of-range port instead of returning -EBUSY. Fix the comparison to
`pn >= maxport`.
