Subject: [PATCH v1 3/3] selftests/mm: remove arm64 nr_hugepages setup for va_high_addr_switch test

arm64 and x86_64 has the same nr_hugepages requriement for running the
va_high_addr_switch test. Since commit d9d957bd7b61 ("selftests/mm: alloc
hugepages in va_high_addr_switch test"), the setup can be done in
va_high_addr_switch.sh. So remove the duplicated setup.
