drivers/net/skfp/pmf.c: Use offsetof() macro

Self-baked macros cause bunch of compile warnings like below:

  CC [M]  drivers/net/skfp/pmf.o
  CC      net/ipv4/fib_semantics.o
drivers/net/skfp/pmf.c:86: warning: cast from pointer to integer of different size
drivers/net/skfp/pmf.c:87: warning: cast from pointer to integer of different size
...

Use the standard offsetof() macro instead.
