CVE-2026-23475

spi: fix statistics allocation

In the Linux kernel, the following vulnerability has been resolved:

spi: fix statistics allocation

The controller per-cpu statistics is not allocated until after the
controller has been registered with driver core, which leaves a window
where accessing the sysfs attributes can trigger a NULL-pointer
dereference.

Fix this by moving the statistics allocation to controller allocation
while tying its lifetime to that of the controller (rather than using
implicit devres).
