Increase the threshold for UploadDeviceDetails failures.

When UploadDeviceDetails is called during a reauth logon,
we write the status (failure or success) and the number of
times it failed to the registry.

When checking if the user needs to reauth or not, if
the registry values indicate failure and it failed less times than
this value, a reauth is forced. But to avoid bothering the user
with constant reauths, if UploadDeviceDetails keeps failing on
every reauth, and if failed more than n times, we skip forcing
the reauth from then on.

Increase this number from 3 to 7 in the hopes that UploadDeviceDetails
finally succeeds, so the dm_token generated with GenerateGCPWDmToken
is uploaded to avoid some authentication failures happening in the
GCPW Extension http requests.
