lok: Avoid deadlock for password-protected doc with gtktiledviewer

Since commit 629bc69708a280b79f07b58adcda8593e22cf422
("LOK: hold the solar mutex consistently for document method calls.",
2016-10-19), the SolarMutex needs to be acquired in
'lo_setDocumentPassword'.

This caused a deadlock for gtktiledviewer when trying to open a
password-protected file, since the callback handler runs in a
different thread there.

Temporarily release the SolarMutex in
LOKInteractionHandler::handlePasswordRequest to prevent that
and make opening password-protected files with gtktiledviewer
work again.
