SolidFire driver does not work with python3

[Erlon R. Cruz]

The SolidFire driver crashes when executing in python3 in the following function:
def _get_account_create_availability(self, accounts)
...
This happens because python3 does not allow the comparison between a list and an integer as it is in this statement:
if self._get_volumes_for_account(acc['accountID']) > self.max_volumes_per_account:
It's also needed to check the logic and the need of this if statement, this block is, logically, never executed:
if len(accounts) == 1:
sfaccount = self._create_sfaccount(accounts[0]['name'] + '_')
return sfaccount
