[PATCH 4.9 77/78] xfs: use kmem_free to free return value of kmem_zalloc

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Pan Bian <bianpan2016@xxxxxxx>

commit 6c370590cfe0c36bcd62d548148aa65c984540b7 upstream.

In function xfs_test_remount_options(), kfree() is used to free memory
allocated by kmem_zalloc(). But it is better to use kmem_free().
