[Intel-xe] [PATCH] fixup! drm/xe: Introduce a new DRM driver for Intel GPUs

[Lucas De Marchi]

drm/xe/sr: Fix too many kfree() on reallocation

When re-allocating the array, the previous location shouldn't be freed.
The issue can be more easily reproduced by reducing
XE_REG_SR_GROW_STEP_DEFAULT. This was crashing kunit during cleanup
on semi-random places depending on the number of save-restore entries.

Jointly debugged with Matt Roper.
