hfi1_rcd_get_by_index assumes that the given index is in the correct
range.  In most cases this is correct because the index is bounded by
a loop.  For these cases, adding a range check to the function is
redundant.

For the use case that is not bounded by the loop range, a _safe wrapper
function is needed to validate the index before accessing the rcd array.

Add a _safe wrapper to _get_by_index to validate the index range.

Update appropriate call sites with the new _safe function.

After changing INIT_UDATA_BUF_OR_NULL() to an inline function,
this does the same change to INIT_UDATA for consistency.
I'm keeping it separate as this part is much larger and
we wouldn't want to backport this to stable kernels if we
ever want to address the gcc warnings by backporting the
first patch.

Again, using an inline function gives us better type
safety here among other issues with macros. I'm using
u64_to_user_ptr() to convert the user pointer to simplify
the logic rather than adding lots of new type casts.
