scsi: libsas: Simplify sas_check_eeds()

In sas_check_eeds() there is an empty branch. We can reverse the test
expression and then remove the empty branch. Also the test expression is a
little bit complex so it deserves an individual function. And make the
continuing prototype lines indented after the opening parenthesis to follow
the standard coding style.
