Subject: [PATCH] xfsdump: avoid segfault in partial_reg() in error case

If we go down the "/* Should never get here. */" path
in partial_reg(), we issue a warning but then continue
with the function.  This calls pi_unlock() twice,
but worse, uses a null isptr:

        if ( ! isptr ) {
... isptr is never set if we get to ...
                /* Should never get here. */
                pi_unlock();
...
        }
...
        /* Update this drive's entry */
        bsptr = &isptr->is_bs[d_index];
        if (bsptr->endoffset == 0) {

>From all appearances, because we unlock on that "never get
here" path, it should just be returning after printing the
warning.  So add that, and we avoid the segfault.

The previous fix to partial_reg() should prevent us from
hitting this in the first place.
