Jing Huang 1769f990fc [SCSI] bfa: vport state machine fix 
Vport state machine does not cleanup associated lport in some states: while
waiting for fdisc response or fdisc failure state. The fixe is to cleanup lport
on vport delete in all states.  In fdisc state, discard fdisc response and
delete lport and wait for lport deletecompletion. in error state, delete lport
and wait for delete completion.
