commit 0ba80d96585662299d4ea4624043759ce9015421 upstream.

The current implementation for loading coalesced KPU profiles has
a limitation.  The "offset" field, which is used to locate profiles
within the profile is restricted to a u16.

This restricts the number of profiles that can be loaded. This patch
addresses this limitation by increasing the size of the "offset" field.
