clk: Initialize max_rate in struct clk_rate_request
Since commit b46fd8dbe8ad ("clk: Zero the clk_rate_request structure"), the clk_core_init_rate_req() function clears the struct clk_rate_request passed as argument. However, the default value for max_rate isn't 0 but ULONG_MAX, and we end up creating a clk_rate_request instance where the maximum rate is 0. Let's initialize max_rate to ULONG_MAX properly.
