[PATCH] xfs: convert dquot iterator map allocation to kmalloc_array()

[William Theesfeld <william@theesfeld.net>]

Convert the open-coded kmalloc(n * sizeof(*p), ...) pattern in
xfs_qm_dqiterate() to kmalloc_array(n, sizeof(*p), ...).  This matches
the convention adopted across fs/xfs/ in commit 910bbdf2f4dXX ("xfs:
convert buf_cancel_table allocation to kmalloc_array") and is the only
remaining instance of the old pattern in fs/xfs/.

No functional change.  XFS_DQITER_MAP_SIZE is a compile-time constant
(10) so the runtime overflow check added by kmalloc_array() folds away;
the conversion is for consistency and to keep fs/xfs/ free of the
deprecated form.
