Update mingw_unlink() to first try to delete the file with existing permissions before trying to force it. Windows throws an error when trying to delete a read-only file. The mingw_unlink() compatibility wrapper always tries to _wchmod(666) the file before calling _wunlink() to avoid that error. However, since most files in the worktree are already writable, this is usually wasted effort. Update mingw_unlink() to just call DeleteFileW() directly and if that succeeds return. If that fails, fall back into the existing code path to update the permissions and use _wunlink() to get the existing error code mapping. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com>

@jeffhostetler I think we should do both. Are you totally opposed to having it in Git for Windows early? It's such a trivial patch, it will be simply skipped from the rebase once it arrives in any official Git version. |

@dscho I’m ok with including in both. i was just trying to not cause you more work later. i’ll update and merge this and send one to GGG and the list on monday. thanks. |

@derrickstolee I'll merge this into GFW as is. Then cherry-pick it into vfs so we can test it there. And then send a patch to the mailing list via GGG. |

Update mingw_unlink() to first try to delete the file with existing
permissions before trying to force it.
Windows throws an error when trying to delete a read-only file. The
mingw_unlink() compatibility wrapper always tries to _wchmod(666) the
file before calling _wunlink() to avoid that error. However, since
most files in the worktree are already writable, this is usually
wasted effort.
Update mingw_unlink() to just call DeleteFileW() directly and if that
succeeds return. If that fails, fall back into the existing code path
to update the permissions and use _wunlink() to get the existing
error code mapping.
