rtlwifi: Remove casts of pointer to same type

Casting a pointer to a pointer of the same type is pointless,
so remove these unnecessary casts.

Around these changes:

o Remove unnecessary parentheses
o Use consistent dereference style (change ptr[0] to *ptr)
o Argument alignment

Done via coccinelle script: (and some typing)
