fix: Make legion_remove return void and set remove_new

The type of .remove in platform_driver changed from

int (*)(struct platform_drive*)

to

void (*)(struct platform_drive*)

in kernel 6.11 to force migration. In version before

.remove_new has type

void (*)(struct platform_drive*)

to allows a migration. We use remove_new to make it
commpatible with different kernels.
