scsi: lpfc: Modify handling of ADISC based on ndlp state and RPI registration

In lpfc_check_adisc, remove the requirement that the ndlp object must have
been RPI registered.  Whether or not the ndlp is RPI registered is
unrelated to verifying that the received ADISC is intended for that ndlp
rport object.

After ADISC receipt, there's no need to put the ndlp state into NPR.  Let
the cmpl routines from the actions taken earlier in ADISC handling set the
proper ndlp state.

Also, refactor when a RESUME_RPI mailbox command should be sent.  It should
only be sent if the RPI registered flag is set.
