[compiler-rt] [NFC] Remove unnececary check from test (PR #112438)

[Vitaly Buka via llvm-commits]

https://github.com/vitalybuka created https://github.com/llvm/llvm-project/pull/112438

Important part of the test to have correct
`ThreadDescriptorSize` after `InitTlsSize()`.

It's not a problem if another test called
`InitTlsSize()` before.

Fixes #112399.
