scripts/checkstack.pl: remove ia64 support

Patch series "Modify some code about checkstack".

This patch (of 5):

After commit cf8e8658100d ("arch: Remove Itanium (IA-64) architecture"),
the ia64 port has been removed from the kernel, so also remove the ia64
specific bits from the checkstack.pl script.
