Description Ralph Böhme 2023-11-13 09:41:24 UTC 
Given two opens on a file:

1. Windows open with delete-on-close
2. POSIX open with delete-on-close set

When handle 1 is closed processing in has_other_nonposix_opens_fn() will not
delete the file as (fsp->posix_flags & FSP_POSIX_FLAGS_OPEN) is false, so
has_other_nonposix_opens() will return true which is wrong.

Have patch, need bugnumber.
