    Cygwin: seekdir: don't set errno
    
    Commit 3f3bd1010455 ("* Throughout, use __try/__except/__endtry blocks [...]")
    introduced setting EINVAL, marked as "Diagnosis".  The reason
    for this is lost in time and space, but looks very much like
    a debug helper which was supposed to be removed before release.
    It's rather pointless, so remove it.
    
    Fixes: 3f3bd1010455 ("* Throughout, use __try/__except/__endtry blocks [...]")
