net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool ops

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.

This is part 1/2 of the fix, as suggested in [1]:

- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.

- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

hinic: use ARRAY_SIZE instead of ARRAY_LEN

ARRAY_SIZE defined in <linux/kernel.h> is safer than self-defined
macros to get size of an array such as ARRAY_LEN used here. Because
ARRAY_SIZE uses __must_be_array(arr) to ensure arr is really an array.

net: convert users of bitmap_foo() to linkmode_foo()

This converts instances of
bitmap_foo(args..., __ETHTOOL_LINK_MODE_MASK_NBITS)
to
linkmode_foo(args...)

I manually fixed up some lines to prevent them from being excessively
long. Otherwise, this change was generated with the following semantic
patch:

// Generated with
// echo linux/linkmode.h > includes
// git grep -Flf includes include/ | cut -f 2- -d / | cat includes - \
// | sort | uniq | tee new_includes | wc -l && mv new_includes includes
// and repeating until the number stopped going up
