Subject: [PATCH 3.18 071/134] autofs: fix error return in autofs_fill_super()

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

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

[ Upstream commit f585b283e3f025754c45bbe7533fc6e5c4643700 ]

In autofs_fill_super() on error of get inode/make root dentry the return
should be ENOMEM as this is the only failure case of the called
functions.
