MIPS: Loongson2: Use clk API instead of direct dereferences

A struct clk value is intended to be an abstract pointer, so it should be
manipulated using the various API functions.

clk_put is additionally added on the failure paths.

The semantic match that finds the first problem is as follows:

// <smpl>

expression e,e1;
identifier i;
@@

*e = clk_get(...)
 ... when != e = e1
     when any
*e->i
// </smpl>
