Summary
xfs: fix finding a last resort AG in xfs_filestream_pick_ag
Details

In the Linux kernel, the following vulnerability has been resolved:

xfs: fix finding a last resort AG in xfsfilestreampick_ag

When the main loop in xfsfilestreampickag fails to find a suitable AG it tries to just pick the online AG. But the loop for that uses args->pag as loop iterator while the later code expects pag to be set. Fix this by reusing the maxpag case for this last resort, and also add a check for impossible case of no AG just to make sure that the uninitialized pag doesn't even escape in theory.
