After changing 'lpfc_hba_queue_depth' value for Emulex HBA, the new value is not shown in '/sys'

Issue

We have changed the parameter lpfc_hba_queue_depth from 1024 to 4096 using the steps in article 23366. After adding the entry in modprobe.conf file, re-created initrd image and rebooted system with new image. It was found that above value is changed from 1024 to 4096 in below file:
```
# cat /sys/module/lpfc/parameters/lpfc_hba_queue_depth
4096
```
But the following HBA specific file in /sys still shows 1024:
```
# cat /sys/class/scsi_host/host2/lpfc_hba_queue_depth
1024
```
