wireless: Remove casts to same type

Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Neatened the mwifiex_deauthenticate_infra function which was doing odd things with array pointers and not using is_zero_ether_addr.
