SolidFire update cache image overwrites accountID param variable

[John Griffith]

bug in the update cache volume in SolidFire driver on delete:

        else:
            # Bummer, it's been updated, delete it
            params = {'accountID': sfaccount['accountID']}
            params = {'volumeID': sf_vol['volumeID']}
            data = self._issue_api_request('DeleteVolume', params)
            if 'result' not in data:

s/ params = {'volumeID': sf_vol['volumeID']}/ params['volumeID'] = sf_vol['volumeID']/

    Fix overwrite of params in SF image cache update

    In the update cache volume routine of the SolidFire driver
    we're unintentionally re-initializing the params variable
    when assigning volID as opposed to just appending another key
    to it.

    This patch fixes that.
