Sometimes VMID targets are not getting rediscovered after a port
reset.
The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the
completion function for the appid CT commands. So after a port
reset, the count of sges is less than the expected count of 250.
This causes post reset operation logic to fail and keep the port
offline.
Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid()
early return cases.
