selftests/mm: fix va_high_addr_switch.sh return value
Patch series "Fix va_high_addr_switch.sh test failure - again", v2.
The series address several issues exist for the va_high_addr_switch test:
1) the test return value is ignored in va_high_addr_switch.sh.
2) the va_high_addr_switch test requires 6 hugepages not 5.
3) the reurn value of the first test in va_high_addr_switch.c can be
overridden by the second test.
4) the nr_hugepages setup in run_vmtests.sh for arm64 can be done in
va_high_addr_switch.sh too.
5) update a comment for check_test_requirements.
This patch: (of 5)
The return value should be return value of va_high_addr_switch, otherwise
a test failure would be silently ignored.
