Correct the USS_PARMLIB healthcheck

The USS_PARMLIB healthcheck compares the active runtime config against the contents of BPXPRMxx and flags any differences.  The problem is that is flags ANY differences, even if they are functionally/semantically equivalent.

For example, if you add the "rwshare" parm to a mounted filesystem via command:

zfsadm chaggr '<uss_filesystem>' -rwshare

(noting that a lowercase "-rwshare" is the only valid option)

But then update BPXPRMxx with

MOUNT    FILESYSTEM('<uss_filesystem>')
        AUTOMOVE
        TYPE(ZFS)
        MODE(RDWR)
        PARM('RWSHARE')
        MOUNTPOINT('<mountpoint>')

The USS_PARMLIB healthcheck then throws an error:

"BPXH041I The following differences were found between the system  settings and the BPXPRMxx parmlib members:

 Changed File Systems
-----------------------------------------------------------
File System: <uss_filesystem>
BPXPRMF0 Value:
 Path: <mountpoint>
 Automove: AUTOMOVE
 Access: RDWR
 Parm: RWSHARE

System Value:
 Path: <mountpoint>
 Automove: AUTOMOVE
 Access: RDWR
 Parm: rwshare

* High Severity Exception *

BPXH040E One or more differences were found between the system settings  and the settings in the current BPXPRMxx parmlib members."


IBM acknowledge the confusion but state that the healthcheck is working as designed: "The purpose of this health check is to detect any difference between the active runtime configuration and the static definition in BPXPRMxx, using an exact, character for character comparison. This includes case sensitivity. While zFS itself accepts equivalent parameter values regardless of case, the health check validates configuration consistency, not semantic equivalence."

Leaving us in the ridiculous situation where a high-severity healthcheck is flagging an uppercase/lowercase discrepancy, even though the case makes absolutely no differences to the functionality.
