Bug#11830755 - UNIT TESTS PFS_INSTR AND PFS_INSTR_CLASS CRASH IN MUTEX CALLS ON WINDOWS

Before this fix, two performance schema unit tests crashed on windows.

The problem was a missing initialization to PFS_atomics,
which caused the crash only for platform not compiled with native atomics.

This fix adds the missing initialization in the unit tests.
No production code was changed, this is a unit test bug only.
