staging: rtl8192e: Remove unnecessary u8 argument cast

Remove the unnecessary explicit u8 casts for u8 arguments in function
calls. These functions have declared their parameters to be of type u8,
so the arguments given to those parameters will be automatically coerced
to u8. Therefore, an explicit cast is unnecessary.
