qed: return status of qed_iov_get_link

Browse Source 
[ Upstream commit d9dc0c84ad2d4cc911ba252c973d1bf18d5eb9cf ]

Clang static analysis reports this issue
qed_sriov.c:4727:19: warning: Assigned value is
  garbage or undefined
  ivi->max_tx_rate = tx_rate ? tx_rate : link.speed;
                   ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

link is only sometimes set by the call to qed_iov_get_link()
qed_iov_get_link fails without setting link or returning
status.  So change the decl to return status.
