Subject: [ 02/46] quota: autoload the quota_v2 module for QFMT_VFS_V1 quota format

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

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

From: Theodore Ts'o <tytso@....edu>

commit c3ad83d9efdfe6a86efd44945a781f00c879b7b4 upstream.

Otherwise, ext4 file systems with the quota featured enable will get a
very confusing "No such process" error message if the quota code is
built as a module and the quota_v2 module has not been loaded.
