Change return values of init_mp_priv from _SUCCESS/_FAIL to 0/-ENOMEM
respectively.
Remove label that returns the required value and return the values
directly as they are set.
Consequently remove now-unnecessary return variable.

The value stored to rfPath during initialization is never read, the
following switch statement re-assigns it a new value on all the
case and default paths. Hence the initialization is redundant and
can be removed.

This patch removes all usage of _malloc() and the function itself. Most
uses are straightforward replacements by kmalloc(..., GFP_ATOMIC),
because this was the definition of _malloc(). In a few places it
was possible to use kzalloc() or memdup_user.
A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL
where possible.
Verified by compilation only.
Initial replacement done by running a Coccinelle script along the lines
of:

type T;
expression E;
identifier V;

- V = (T) _malloc(E);
+ V = kmalloc(E, GFP_ATOMIC);
