[ Upstream commit289460404f] The function-local variable "delay" enters the loop interpreted as delay in bits. However, inside the loop it gets overwritten by the result of mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in cells. Thus on second and further loop iterations, the headroom for a given priority is configured with a wrong size. Fix by introducing a loop-local variable, delay_cells. Rename thres to thres_cells for consistency.
