Removed several uses of name.split('.')[0] in SoftLayer driver.

This code is breaking when server names with multiple periods are used - for
example, name=server1.prod.dc1 domain=example.com. Simply "split and use first
one isn't the reverse operation of "'.'.join([name, domain])" which is done
when VM is created here: 9dcd11c155 (diff-ac8112a3f8d2ebde0edf104797fe64d7)

We've been running with these changes for a while and don't have any issues
creating or destroying instances.

The caveat that some operations (such as destroying) through SoftLayer API
require hostname (without domain) is already documented in Salt and still
applies.
