[PATCH] staging: rtl8723bs: Remove unnecessary cast in kfree

[Amitoj Kaur Chawla <amitoj1606@xxxxxxxxx>]

Remove unnecassary casts in the argument to kfree.

Found using Coccinelle. The semantic patch used to find this is as
follows:

//<smpl>
@@
type T;
expression *f;
@@

- kfree((T *)(f));
+ kfree(f);
//</smpl>
