KVM: selftests: Make reclaim_period_ms input always be positive

reclaim_period_ms used to be positive only but the commit 0001725d0f9b
("KVM: selftests: Add atoi_positive() and atoi_non_negative() for input
validation") incorrectly changed it to non-negative validation.

Change validation to allow only positive input.

Fixes: 0001725d0f9b ("KVM: selftests: Add atoi_positive() and atoi_non_negative() for input validation")
