KVM: selftests: Use non-atomic clear/set bit helpers in KVM tests

Use the dedicated non-atomic helpers for {clear,set}_bit() and their
test variants, i.e. the double-underscore versions.  Depsite being
defined in atomic.h, and despite the kernel versions being atomic in the
kernel, tools' {clear,set}_bit() helpers aren't actually atomic.  Move
to the double-underscore versions so that the versions that are expected
to be atomic (for kernel developers) can be made atomic without affecting
users that don't want atomic operations.

Leave the usage in ucall_free() as-is, it's the one place in tools/ that
actually wants/needs atomic behavior.
