arm64: Clear the initial ID map correctly before remapping
[ Upstream commit ecc54006f158ae0245a13e59026da2f0239c1b86 ]
In the attempt to clear and recreate the initial ID map for LPA2, we
wrongly use 'start - end' as the map size and make the memset() almost a
nop.
Fix it by passing the correct map size.
Fixes: 9684ec186f8f ("arm64: Enable LPA2 at boot if supported by the system")
