Fixed getLocalFile() condition for x-send-file

Until now, addSendfileHeader() was called even when no x-send-file
headers were set. Even though the method itself doesn't do anything,
a call to getLocalFile() was done and would trigger a full download
when using external storage.

Additionally, the storage resolution code is wrong and always
returns the local storage of the root filesystem, which caused the code to
be run anyway.

This commit fixes both issues.

[encryption] fix redirectToErrorPage() call

Check which permissions are possible to re-share a file

When NetBIOS is blocked or disabled, a smb::look() call can still get
the list of shares from smbclient, even though the name resolution at
the end of the command fails.

This fix makes it ignore the connection error if we already got the list
of shares.

Fixed #5860
