[PATCH 4.4 56/56] PKCS#7: fix unitialized boolean want




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

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

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

commit 06aae592425701851e02bb850cb9f4997f0ae163 upstream.

The boolean want is not initialized and hence garbage. The default should
be false (later it is only set to true on tne sinfo->authattrs check).

Found with static analysis using CoverityScan
