Don't block all requests to switch data

Browse Source 
This switchtes the data even if there are requests still running on the
old data. osrm-datastore then waits until all of these old requests have
finished before freeing the old regions.

This also means that osrm-datastore will return with an error if there
is a data update currenlty in progress.
