Add the FLOGI cmd to the list of commands which are allowed to retry.

we observerd log below during failover operations. With this patch all
is good. FLOGI is retried and succeeds eventually.

Daniel,
We want to look more closely at this. We do have FLOGI retry logic, but
perhaps not tied to lsrjt logical busy. We have had OEM requirements as
to how we do FLOGIs and respond to different status's. This change may
disrupt those requirements (works for this config, not others). I'll get
back to you shortly.
