staging, wlags49_h2: Remove unnecessary casts of void ptr returning a…

…lloc function return values

Hi,

The [vk][cmz]alloc(_node) family of functions return void pointers which
it's completely unnecessary/pointless to cast to other pointer types since
that happens implicitly.

This patch removes such casts from drivers/staging/wlags49_h2/
