Corinna Vinschen 21a2c9db69 Cygwin: SetThreadName: avoid spurious debug message
The following debug message occassionally shows up in strace output:

  SetThreadName: SetThreadDescription() failed. 00000000 10000000

The HRESULT of 0x10000000 is not an error, rather the set bit just
indicates that this HRESULT has been created from an NTSTATUS value.

Use the IS_ERROR() macro instead of just checking for S_OK.

Fixes: d4689b99c686 ("Cygwin: Set threadnames with SetThreadDescription()")
