drm/xe/devcoredump: Update handling of xe_force_wake_get return

xe_force_wake_get() now returns the reference count-incremented domain
mask. If it fails for individual domains, the return value will always
be 0. However, for XE_FORCEWAKE_ALL, it may return a non-zero value even
in the event of failure. Use helper xe_force_wake_ref_has_domain to
verify all domains are initialized or not. Update the return handling of
xe_force_wake_get() to reflect this behavior, and ensure that the return
value is passed as input to xe_force_wake_put().

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()

v5
- return unsigned int for xe_force_wake_get()

v6
- use helper xe_force_wake_ref_has_domain()

v7
- Fix commit message
