Precedence: bulk

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.

Fixes: b46fd8dbe8ad ("clk: Zero the clk_rate_request structure")
